Home Forums Hunting & Shooting Handguns What powder for 10mm?

I think it's because of people wanting to turn it into something it's not, a semiauto 41magnum.
In my case i got the glock 20 before i got the brass and dies to reload it.
I bought two boxes of factory remington 180grain bullets. Looking at the box they were turning about 1000fps. Can you say .40s&w?
I still have the boxes, minus about six rounds. The other interesting thing is right out of a lyman reloading manual is 165gr silvertips at 1200fps out of a s&w .40.
what i wanted was the norma 200grain at 1200fps load. When i figured that out, i pretty much stayed with it.
That's in the light 41magnum class, certainly 41special class, and what i am most happy with 1000fps to 1200fps.
And i load a lot of stuff in that range from 45colt, 44magnum, 44special, 41magnum, 41special etc.
the atvantage to the 10mm is that 14round mag capacity in the glock 20.

I find the recoil of a 180gr bullet @ 1300fps very controllable and very accurate from my Glock 20 so that's what I want to match, not make it a heavy 41 magnum. I have plinking loads for all my handguns I load for but when I hunt with them it's with more or less full power loads.


44 magnum - 275gr @ 1250fps, 300gr @ 1100fps or 240 @ 1400fps. These are my recoil limits with the 44 magnum.
30/30 - 170 @ 2000fps


I've tried the 300's @ 1300+fps and I just don't like the recoil from the 44 magnum. I've shot the 454's in single actions, heavy 45LC's, 480's and 475 Linebaugh's and I'm glad other people can shoot them and enjoy them but I can't.

I bought a thousand of the powder coated 200 grainers from Missouri Bullet Company. Great price, great bullets.

I have been using AA#9 for a long time in a few calibers. 10mm, 44 Mag and .475 LInebaugh. Its a good one and has been proven consistent and
accurate in my loads.

I wonder how these are as far as being a good flat nose meplat?

That profile is fine, but I suggest saving yourself a bunch of trouble and just go with coated bullets to start with, and not from Midway because they don't have what you'll want.. They aren't much more expensive, if at all, and have no downsides compared to the bullet you linked to.

I am ordering that coated ones from Bayou bullets. I was just wondering if the one from midway would have a wider meplat for hunting?

Stay away from fired Federal brass. Much of it is military, and the strength is variable. Had one rupture. Took out the magazine catch, but that was all, fortunately

my experince raw speed #9 , over all best accuracy , reliabilty ? longhot BE 86 pretty good to to duplicate factory loads

You'd have better results with a 180 XTP for that, IMO.

Bumping this back up.


I just got around to burning through my Underwood 180 XTP's and some other ammo so I set down and started to chrono some loads from my Glock 20.


Underwood 180 XTP's average 5 shots 1359fps - Glock 20 Storm Lake 6" barrel

Sig Brass
WLP
Longshot
180 XTP

Average 5 shots

9.0grs - 1300fps
9.3grs - 1344fps
9.5grs - 1374fps - holy crap


Tomorrow I'm going to shoot 9.0grs, 9.2grs and 9.3grs for accuracy.

I did some shooting today and 9.2grs is where I'm going to settle. Accuracy was very good.

Sig Brass
WLP
1.260" OAL
FCD 1 turn
Longshot - 9.2grs


Glock 20 - 6" Storm Lake


Chrono'd 5 rounds after some accuracy shooting - 1338, 1328, 1333, 1333, 1334 - 710lbs of energy

I had a Glock 20 a few years back. Tried Universal, Unique, Titegroup, and Power Pistol with it - all worked well. Had problems with the Glock, including case ruptures, using a Lone Wolf barrel. Went to a 6" Glock barrel that seemed to "work" much better, but sold the gun when I was dealing for a .480 Ruger, so didn't experiment with it a lot. I have a EAA Witness 10mm now, so I'm starting over with this caliber. I like the 10mm as a woods-carry and hunting gun, but most of my handgun hunting now is for hogs, at fairly close ranges. I still want to try an RIA 1911 in 10mm - ought to be very good for what I use a 10mm for.

A friend has several of the EAA guns and really likes them. He's killed a few hogs and deer with his using the 180 XTP.

You have her going on now Bearcat, I've got all the 200 gr nosler HP's shot up, it'll be 200 gr XTP's and Longshot from now own, have settled on an even 1200 fps in my all steel DW ramped 5" 1911, what a fun, and accurate gun to shoot.

Uh, Mike, it's no surprise you had case ruptures if you were trying to load full power 10mm with those powders. You gotta put more research into burn rate than that; those fast powders peak pressure quickly in that case; they're fine for mild loads but terrible choices for full power and can be dangerous.

Actually, I NEVER push my loads to "full power" - in any caliber. I followed "published" loads, backed off a bit.

What powder would you recommend??

Mike Holmes

You didn't get case ruptures from mild pressure, unless you found some really bad brass or did something wrong to the gun. Those powders you used produce very rapid pressure spikes, and it doesn't take much of a change to go from mild to dangerous. Anything more than top 40 S&W velocity in the 10mm with those powders is asking for trouble in my experience, and if you're only loading below that level, why use the 10mm at all...

Read my comments earlier in the thread about powders. AA9, AA7, Longshot, and Blue Dot are your prime choices.
