10mm powder

Quote:

What gun are you shooting it out of?
That was my first question. I know you mentioned "both short and standard sized barrels." A little more specificity would be helpful.

Quote:

If you're looking for middle of the road power, 231 is fine.
I'm gonna take some issue with that. My load style leans toward fast powders more than most. But W231 is awfully spunky for 10mm with a 200 grain bullet. Yes, you can do it and it can yield some mild ammo. But you're treading in a really spooky forest with the W231/200gn combo. I've loaded AA#2 (ever so slightly slower than W231 IMO) under 180's. It was a good running mild round. But even that combo made me a little nervy; with my 30 years loading experience. Going with an even faster propellant, with an even heavier bullet is concerning to me. Just my opinion.

AA#9 is going to be mentioned a lot (already has). And it's a good way to go. Myself, being a little more fast powder centric, and knowing you mentioned a shorter barrel, I'd recommend AA#7. It won't yield quite the velocity as #9, but it'll give you a less flashy round, and with noticeably less recoil. I would consider it to be a more "balanced" round. But it's a matter of personal preference.

You mentioned Power Pistol. Power Pistol is good stuff. But it is a touch fast for this application. It's a little faster than AA#7, so I think it's stepping out of the circle of "ideal" propellants. Now if you were loading 165's, I'd say it would be a dandy choice. Power Pistol's wheelhouse is 9mm & 40 S&W. It's a little spunky for the big 10.

I don't have experience with Longshot.

I'll finish by saying this: if you're loading 200's, might as well load 'em kind of juicy.

I've got a G20L and Power Pistol works very well in the longer, 6" barrel giving me a few hundred fps faster velocities with both 165 and 180grn bullets over my neighbor's stock G20.  Further, I've got no issues with max loads of it showing any pressure signs.  I've got a nuclear level load that just shows a bit of primer flattening but produces 165grn velocities approaching 1,600fps in my 6" G20L.  All my Power Pistol loads include LP Magnum (CCI 350) primers as not only do they produce higher velocities but lower SD and ES than regular LP primers.

ETA:  I've found that Blue Dot doesn't give me any more velocity out of my 6" barrel, however, it does produce a spectacular flame! I'm talking 'light up the night' size flame even at less than a full loads.  In addition, while the Power Pistol gives a roar the Blue Dot is more of a crack.  I also use Power Pistol in my 45 Super where a decent load produces 1,307fps pushing a 200grn bullet out of my 6" G21L.  All in all, I find that 40s&w, 10mm, and 45 Super do well with Power Pistol without abusing the brass.

Thread: Best General 10mm Powder

    Best General 10mm Powder

    I'm building a 10mm because i don't have one, haha, and was wondering what others who have reloaded for it view as the best general all around powder for cast and jwords. I have looked online, looked through the manuals etc. I have several powders on the shelf that will work including Power Pistol but was thinking someone else might have some better insight to save me time and powder which is in short supply.

    I vote Hodgdon Longshot. Runs great with jacketed and cast. My favorite.


  • 12-17-2020, 06:24 PM#3

    My favorite is the discontinued HS7. If I were out of HS7, I would look at Power Pistol or CFE Pistol. In revolvers I use 2400 and 296 in 10mm if I want max performance.

    Since getting back into 10mm a few years ago I’ve come to like BE-86 a lot. Meters well, allegedly flash suppressed, gets 200gr up to 1200fps in my 5” SR-1911 without drama and reasonably available. It works well in 9mm. Probably in other calibers too but I find myself hoarding it for my 10mm guns...

    After getting a 10mm a few years ago, I searched the data and decided on Longshot. Meters great and gives great velocity or can be loaded a little lighter if needed.

    All depends on how hot you load it. For low power I just shoot 40S&W out of my RIA 1911 in 10mm. For mid loads there are tons of powders you can use. longshot. Power Pistol, HS6 but for full loads you need something slower like #9 or 2400. I use shooters world heavy pistol which is pretty much the same as #9.


  • 12-18-2020, 07:12 PM#11

    What do you need your 10 to do for you?

    Go bang. Target and plinking, I have revolvers to hunt with and it's not going to be a carry gun for me. I don't envision top end loads for more than to see what works or to try them out, most of the shooting will be mid range or lower and majority cast.

    If you are just target shooting, just use W231. It works well in the ten and is accurate.


  • 12-18-2020, 08:29 PM#16

    I have:
    231
    Promo
    Bullseye
    HS7
    Unique
    Power Pistol
    Titegroup and a few others.

    I'm just trying to come up with a general powder to use for all around stuff.

    Another vote for blue dot. I like to shoot full power out of my 10. If I want softer shooting, I shoot the 40. I also use blue dot in the 40 for what it's worth.
    I also like it for lighter boolits and bullets for .44 mag

    DefaultBest/Preferred Powder For 10mm

    I have just started to put together what I need to reload 10mm ammo, which is new to me vs what I have reloaded for many, many years, .45acp, .45 Colt, .454 Casull and .44 Mag & Spl.

    What powder do you 10mm reloaders prefer, especially for full power loads? I am not asking for any receipies, just your preferred powder, for Mid-Range/Plinking Loads and Full Power Loads.

    If anyone wants to mention their Pet Loads, it will be appreciated.

    There is no "best" for any caliber. But some good powders IMHO are Power Pistol. HS 6. Longshot, CFE pistol, Unique or other brands along the same burn rates. Not to fast, not to slow

    Power Pistol is my go to powder for 10mm. Meters great, economical, can run mild to wild.

    I shoot 180s and 200s and have had good results with BE-86 for medium-power SD loads and Longshot and AA-9 across the board. LS and AA-9 are good for "real" 10mm loads.

    Both BE-86 and AA-9 are flash suppressed.

    I like Blue Dot. In my Delta, 10 grains with a 180 grain HAP yields 1,220 fps, and 9 grains with a 180 grain lead flat point yields 1,135. The R-P 180 FMJ runs 1,150 for reference.

    The R-P 180s look (flash) and feel like a PP load. Commercial PP is known as BE-84. I should pull one apart and weigh the charge.

    Some love 800X but I just haven't gotten the accuracy out of it I desire. A#7 & 9 do far better. BlueDot can be very good as well, but the AA powders meter so much better.

    But are then saying you get faster velocity from slower powders?? Can that be?Also how is that recoil

    I load 12.6 gr of AA-9 under a 200 gr XTP for 1200fps out of my 5" Rock Island 1911.

    Recoil is manageable; no worse than .40 out of a plastic gun. I can't complain about it. I'm also using a 26# spring to save the brass from getting chewed up.

    The best powders for full power loads with 180 and 200gr;

    800-X
    Longshot
    3N38
    Blue Dot
    AA #9

    Power Pistol
    AA #7

    Power Pistol and AA#7 will get you about 90% of what the other powders can provide, but I've found them to be very accurate.

    Which ever ones you can find you'll be happy with. Your gun will probably have preferences.

    I don't load 10mm, and my only experience is firing a friend's. However, were I to reload the 10mm, I'd consider AA5 and maybe AA7 first. Unique would also be a likely possibility.

    Can't go wrong with Power Pistol or Longshot with 165gr. JHPs. They're also fine with 180gr., along with Bluedot. Surprisingly I got some very good accuracy with 13.0gr/2400 & 180gr Nosler JHP, in my 1076.

    Lot's of very good information in this thread. I really appreciate all the input and opinions.

    I'll be loading 180gn bullets and I am thinking of buying one pound each of #7 and 800X to try out and see what I come up with. from what I have read, I get the impression that #9 is better for heavier 200gn and up bullets.

    What a difference a forum makes. Here the most suggested powder is Power Pistol, elsewhere it was AA#7.

    I'm in the AA#7 camp since my real favorite HS-7/W571 is no longer available.

    You hit the nail on the head brother!

    After much consideration, and I have changed my thinking several times now, but now I am locked in! I will be picking up one pound of each, Power Pistol and AA#7. That way I can test both powders and see what works best for us.

    I truly appreciate all the input received on both forums.

    But on the other forum the title of thread was:

    "What Powder for Full Power 10mm Loads"

    Kinda like what is the best gun or car to buy.

    Per Alliant, #9 is mo better than #7

    Any reloading manual will give you data to go forth and experiment. Also depends on what bullet and weight.

    My favorite for the 10mm is Longshot. Use the formulas in the Hodgdon manual. My S&W 610 (6 1/2") loves a near max load of Longshot with 180 gn. Montana Gold flat-points or XTPs. Cronos right at 1350 FPS out of the 6 1/2" barrel and is very accurate. This was my best bowling pin combo. Pins did a double back flip off the table.

    Well I bought a 10mm to shoot, well 10mm loads. If I wanted 40, why bother with the bigger gun? I don't shoot 38sp out of my 357mags either. Yes, slower powder will get you higher vel with less pressures, but we all know that.

    In this review, "Kimber 10mm Model 1911" - Handloader #253, & handload data, AA#9 had the highest velocity for any 180gr JHP (Speer 180gr GD) bullet. Their charge of 15.0grs though, is higher than what's listed in Accurate'sreloading guide (13.5gr).

    But how did the "Kimber" handle all that power

    Ask 10 handloaders the best powder for something and get 13.5 answers.

    This might help: Real Guns - Dan Wesson's Commander Classic Bobtail II

    Without looking, I'd probably go with either VV N-105 or Longshot. Power Pistol and Blue Dot ought to be good.

    BTW, VV N105 narrows any perceived gap between the 10MM & .40 S&W.

    When it's available in CA, I will buy a Delta Elite. I think that it'd be the perfect trail gun. I'd love to won a Model 57, but I've yet to carry any handgun that's as easy as a 1911A1-stlye handgun.

    Again, if you only want 40 vel, aa#5 & unique are just too fast. AA#7 is pretty good, but still a bit fast for best vel.

    Oh Well! I stopped at five different local area B&M gun shops yesterday and could not come up with even one pound of either Power Pistol or AA#9.

    I am not too upset about the Power Pistol, as I have several other powders in my stash that will work well, from what I have read for med-range plinking loads. I really wanted the #9 for full power loads.

    Has anyone ever used 296 or 2400 in 10mm for full power loads? I have a lot of both in my stash that I use for .44 Mag & .454 Casull.

    BTW, pricing at the B&Ms has really gone crazy!

    I don't know anyone who uses either but that doesn't mean it can't be done. Lyman doesn't have data for either. Hodgkin doesn't list data for W296/H100 either. Alliance has data for 2400 with only one bullet and only a specific bullet in that weight, the 180gr Speer GDHP bullet.

    Usually when there is little to no data for a powder/cartridge combination there is a very good reason.

    You could try compressed loads of 2400, but I doubt you get the vel you want. It is about the same burn rate as AA#9, but bulkier so limits how much you can cram in the smaller 10mm case. No AA#9, find some Longshot or BlueDot.

    My biggest complaint working up loads for my 10's is just about all the bullets are designed for 40 S&W velocities and don't hold together well when pushed to 10mm speeds.

    I've only worked up loads for 180, 200 & 220 gr bullets but I'll pass on my findings.

    180 grain bullets: (Xtreme HP, Hdy XTP, Gold Dot)
    Here, Blue Dot is the hands down accuracy king. I've read on many forums where 10.4-10.6 is somebody's "pet load" so I worked it up and discovered...yes, it's true. In my case, I've settled on 10.4 gr. It's not exactly a "full power" 10mm load as it barely cracks 1200 f.p.s. in my Glock 40 or my RIA 6" Match Pro and only does 1165 in my 5" RIA but this load groups 2.5" (or better) at 50 yards. I shoot more Xtreme HP's + BD than the rest combined.
    My "do all" deer/defense/woods load is the Gold Dot loaded with 9.0 gr of Longshot for 1300+ f.p.s. Longshot gives horrible accuracy with every other bullet I tested but still manages around 4" groups at 50 yards with the Gold Dots.
    Honorable mentions go to Accurate #7 & #9 (Mag primers), Power Pistol and BE-86.

    200 grain bullets: (Hornady XTP, Xtreme FMJ)
    Here, Accurate #9 is my favorite. I won't divulge my load as it was worked up in the 90's and the data back then was a bit warmer than Accurates current 12.5 gr max load. Chronos 1200+ f.p.s. and groups 3"-4" at 50 yards in my 10's. Again, I recommend CCI 350 magnum primers.
    Honorable mention to Longshot and Accurate #7. They're not quite as fast or as accurate but you use considerably less of it.

    220 grain Xtreme FMJ
    Here I was in uncharted teritoritry but using the factory ammo pull downs from another fourm, I found data for Longshot. Again, I won't divulge my data as I have never seen printed, tested data for this bullet. So far, I've worked up to 1050 f.p.s. with no signs of excessive pressure as I'm a full grain under what the ammo compainy swears is within SAAMI pressure limits. Eventuly, I will also be testing Accurate #7 with this bullet.

    Hope this helps.

    Jeff

    Huh?

    Makes no sense. A bullet, say an XTP or Barnes, Speer falls apart going a 100 or even 200 or so fps faster ?? How many XTP bullets have been fired from rifles in other calibers at even faster velocity?

    How do all the upper end ammo makers do it then?

    Both BE-86 and AA-9 are flash suppressed.

    My research shows that A9, A7, HS-6, and Universal all are very-low-flash powders, while Longshot, 800-X, and A5 are high-flash powders.

    Muzzleflash by Jeffrey Behr | Photobucket

    After experimenting with the Big10 this spring and summer, I find HS-6 to be excellent all-around for bullet weights thru 165 or maybe 180, and A9 and VihtaVouri's N105 to be excellent for high-power 180s and heavier. I achieved my highest velocities with 180s with N105, but I've NOT tested it for muzzle flash.

    I highly recommend 10mm-firearms.com - Indexas dedicated 10mm forum.

    As fredj338said, AA#9 is a little less bulky than 2400. 13.5gr/2400 would have the same volume as (the previously mentioned) 15.0gr/AA#9.

    The older Alliant reloading guides (ie: 2000 & 2003) list (5) different bullet weights with 2400.

    If you can't find any AA#7 give Longshot a try. It's my second choice for the 10mm.

    How do all the upper end ammo makers do it then?

    10mm Ballistics Chart | Ballistics 101
    I'll break it down for you and try to make some sense of it for you. Call it Ballistics 102 or What happens to bullets when they hit something. aka Terminal Ballistics.

    Expanding bullets are designed from the manufacture to work within a certain velocity window. With some rifle bullets, that working velocity window is over 1000 f.p.s. In most handgun bullets, that window is usually around 500 f.p.s. (some less some more)
    If your impact velocity is below that minimum, the bullet fails to expand and acts more like a solid or FMJ. Think of using .429 bullets designed for the 44 magnum in a snub nose 44 special. Your muzzle velocity is all ready 100 f.p.s. or more below the working velocity of what the bullet was designed for. You end up with little to no expansion and over penetration.

    Go above that limit, and bullets will rapidly expand and even fragment or tumble, limiting penetration.

    Thankfully in the case of .429 bullets, their are at least a few bullets available that are designed for the lower 44 special velocities.
    However, in the case of .400 diameter bullets, since the 40 S&W is vastly more popular than the more powerful 10mm, just about all the bullets made are designed for the lower velocity 40. The last commercially available true 10mm bullet is the Winchester 175 gr Silvertip. The same bullet that is loaded in the factory ammo at 1290 f.p.s. Almost never available and extremely expensive when you do find it. Two bullets available in factory ammo only, are the Federal trophy Bonded and the Sig V Crown 180 gr made by Sierra. Sadly the only time these bullets are available as components is when someone does a pull down.

    The only 40 bullets that do work, (barely IMO) most of the time, at 10mm velocities are the Hornady 200 gr XTP, the Speer Gold Dot 180 gr. I've heard the Nosler 200 gr and the Speer 165 gr Gold Dot also work but I've never tested them.
    Several of us routinely e-mail bullet companies asking them to release a true 10mm bullet but they very politely decline because they don't want the negative feedback from someone complaining they won't expand when fired out of his 40 S&W.

    So, how do the boutique ammo makers do it?
    Simple, they lie...or omit certain truths.

    If you don't wish to spend the time and money testing yourself, do a search on you tube for 10mm gel tests. Here's a link to some 10mm only tests by one of them. 10mm gel tests - 10mm-firearms.com

    Hope this helps.

    I well aware of bullet expansion or performance when striking an object but that is not what you said.
    You said:

    "My biggest complaint working up loads for my 10's is just about all the bullets are designed for 40 S&W velocities and don't hold together well when pushed to 10mm speeds."

    Which says they do not hold together at SPEED, not at impact.

    Maybe with hunting animals the nuances may matter but for SD ammo will the bad guy know it is a Hornady or Gold Dot?


    It is all how many Angels can dance on a head of a pin.

    Carry on with your ballistic testing on gel and water bottles or whatever floats you boat.

    Winchester, Rem, Hornady, Federal all not boutique makers.

    Sure listed FPS obtained is not usally even close due to 10" test barrels and such

    All the ammo makers lie.
    You tube is the source of all facts.

    I picked up a set of dies and some 180 XTP's for my Glock 20. I have Storm Lake 4.6" and 6" barrels and I have access to Longshot, Blue Dot and AA #9. I am looking for full power stuff to be around the Underwood 180 XTP load I'm shooting right now just over 1300fps. I will probably try the 200gr stuff, either XTP or WFN later on also. I was hoping 2400 would work but I don't see it mentioned much at all for the 10mm.


    I have Unique and a few other powders for low power stuff.



    Thanks

    I don't have any experience with any of your powders. What I've used, and like a lot, are AA#7 and Ramshot Silhouette. The AA#7 left nothing to be desired with the 180 gr. XTP's . The Silhouette I use with the Barnes X, 155 gr. bullets.
    Be very careful loading for the 10. I've had pressure tested load data bulge cases when well below maximum with AA#2. It is no longer listed as a powder for the 10mm BTW. It was at one point. The other thing is that brass can vary some in wall strength, etc. I've even had some WW brass that was so short it sometimes wouldn't fire my loads. E

    The powders you have listed are the best of the best... I have been using AA #9 but just got some Blue Dot and Longshot. Longshot is what supposedly some of the boutique manufacturers are using for heavy cast slugs...

    ps..if you don't subscribe to LoadData.com is is well worth the money...it is like having all the loading books on line... They have hundreds of loads for the 10mm...

    Also I forgot that PowerPistol is another good powder for the 10...

    Tread carefully. 1300 fps may not be obtainable safely.

    Of the 3 you mentioned, I'd start with #9.

    Looking over at LoadData.com, the only power that has several listing as to making 1300+- fps is #9. Blue Dot only has one...

    Starting loads with #9 is about 13.0 and tops out at 15.0 which gives 1300-1320 fps depending on who was doing the shooting.

    Thanks for the info. I was leaning towards #9 as it seems to be a little more flexible.


    I think the shop has some PowerPistol as well.

    I have used 2400 under 180 grain XTP's for some years now in 10mm. I'm getting 1200 and change and have never had a problem in my Glock 20 after I put in a heavier than stock recoil spring. Disclaimer: I use new Starline brass with the XTP's, after the first use they are reloaded with a somewhat (not much) milder 180 grain plated bullet load and are tossed after that use.

    I have a 22lb recoil spring in mine.


    I just loaded up 6.4gr of Unique just to get my dies setup and they functioned great, were accurate but very mild. We have some strong storms rolling through so that was all I could get accomplished tonight.

    #9 is absolutely the best choice there, although the other powders you mentioned are good as well. In that bullet weight range (really 165-200+gr) #9 gives you top velocity at max pressure with max case fill. It's only failing is just the quantity of powder it requires, so you get fewer shots per pound. Otherwise it's pretty much perfect; it's almost like #9 was made specifically for full power 10mm.

    You should definitely be able to get 1300 fps easily with that 180 XTP in a G20. Use this at your own risk, but I have worked up to 15.0gr with that load for 1385 fps from my long slide G20. 11.0gr of Blue Dot gave pretty much the same velocity. You will want to use the heaviest recoil spring you can get.

    All of my 10mm's like AA-9 the best with Blue Dot coming in a close second!

    i like accurate for another reason, it meters well right to the dot.
    from a couple of years ago
    glock 20 with kkm barrel and another six inch kkm usine AA#9 13grains and 200gr xtp
    1. 1212 six inch 1298fps
    2. 1211 1285fps
    3. 1218fps 1266fps
    4. 1213 1283fps
    5. 1224 1254fps
    these were all seated to 1.260 col
    Same loads out of a ruger buckeye special convertible with a long barrel
    1. 1318
    2 1302
    3. 1305fps
    4. 1290
    5 1301
    6 1295
    one of the side benefits is they were pretty tight velocity wise round to round except in the six inch for some reason showing a little more deviation. what i was really after was the old norma load of 200grains at 1200fps, and i stopped at the above.

    same gun using 180gr xtp''s and AA#7 10.5grains oal of 1.260
    kkm standard length and six inch
    1.1157fps 1268fps
    2. 1188fps 1265fps
    3.1198fps 1291fps
    4. 1173fps 1263fps
    5. 1178fps 1277fps

    i should add all new starline brass and heavier recoil spring.

    Ron it's probably obvious to you, but worth pointing out for everyone that your AA#7 load pressures were significantly higher than with #9. Besides being a faster powder (pressure peaking earlier) #7 in the 10mm doesn't always show many pressure signs until it's really too hot. #9 in comparison is more user friendly and capable of higher velocity at safe pressure.

    Though I don't even own a 10mm anymore (eventually went in the 45 Super direction), in the 90s I did a lot of work with the 10mm and full power loads. I've used all of the powders you listed and AA#9 is the best of those for highest velocity. But THE BEST powder I ever found in terms of maximum velocity at reasonable pressures was 800X. At the time, Mike McNett and I were exchanging a lot of information on 10mm loading over at GlockTalk. A little later he quit his job and started DoubleTap ammo (I think in his garage?) with a full house 200 grain 10mm load. I don't know for sure, but I think he probably started DoubleTap with that 800X load.

    I found a nice accurate plinking load with a 180 over 6.4grs of Unique. I picked up some AA9 and will start with it soon.

    800X does work well, but has two problems - it meters like cornflakes, and pressures look good right up until it spikes crazy high, similar to AA#7.

    So far everything Yondering has said is my experience as well.

    No more 800X for me.

    BlueDot,? well the 10mm is too close to the internals of the .41 Magnum for me to use it. (different bullets weights granted)

    You can learn a lot from McNett.


    Longshot is very safe. My favorite now.

    AA#9 ,can't beat it.


    Starline brass only. Toss away the others if you want nuclear loads.

    I use/like Blue dot and AA#9 for velocity & accuracy.

    Prefer AA#9 as it meters better than Ble Dot.
