Home Forums Reloading Handgun Reloading 10mm

Been loading some 10mm loads for defense against Wyoming bears and smaller stuff. Been using aa9 with 200 grain to bullets. Best accuracy from the Glock 20 was right around 1000 FPS and 11.2 grains. Is there another low flash powder that would go a bit faster?

What bullet weight?


I’m using 180’s and 9.2grs of longshot for 1340fps.


Have a load wrote down from gunner500 if I wanted to try 200’s.

8.5grs longshot and 200xtp 1200fps

I’m running 10.8 grs. of AA#7 and Hornady 180 XTPs in my Springfield TRP. They’re averaging 1185 fps with zero muzzle flash.

Sorry fellows I am running the 200 xtp

A 200 grn xtp using 7.8 of Longshot gets me 1125 fps out of a Glock 20, stock barrel, with 20# spring.

Same load and gun but with a 6 inch KKM barrel runs 1190 fps.

Have any of you noticed hodgon does not list longshot with their 220gr load data? I should call and ask why, everything I read longshot is the powder to use with 220’s..

So far I've gotten 1176fps with 2400 and 1229fps with Longshot using 195gr hardcast WFNGC in my M610. I don't think Longshot is a low flash powder, but what about 2400? I've yet to work up #9 loads with this projectile.

I haven’t tried 2400 reason why every that’s shoots 10mm says LS, blue dot, #9 and 800x are the ones to use. I’m no 10mm expert so I’m going with what everyone else is using. But I’m trying out some Winchester 244 and #7.. I really don’t want to get into my last 2 lbs of 2400 chit be hard to come by right now.

That's how I feel about BD. I'm down to my last pound, that's why I'm futzing with 2400 in my 10mms.

I need to go try these 180’s I have loaded with Winchester 244. Or just stick with longshot and go buy 2-3 more lbs of it and be set for a long time..

I use Blue Dot with 220 gr Hard cast

John and Kurt,
The lady carries a glock29, because she's better with it, than my 357 mag sp 101.

As you guys know, winter moose will stomp the fk out of a dog team, rather than leave the trail. So a glock 10mm is pretty common among mushers.

We cant use hard cast, for risk of over penetration and killing a dog. But penetration still matters.

In the below zero weather, I've found be-86 works best.
Long shot and blue dot are shot gun powders and leave a huge fkn fireball out the little glock during night runs.

Be 86 has a flash suppressant and it works very well.

AA#9 is too slow from the 3.7" barrel in below zero weather.

I load 8.4 grains of be-86 under a 200 grain 10 mm swift A-frame for exactly 1200 fps.

If you tear apart an underwood 200 grain load, you will find 8.7 grains of be-86 under that 200 grain xtp.

I've put a few finishing shots through moose with 44 mag, 357 mag and glock 10 mil. These were hard cast and swift a-frames. I can tell you the controlled expansion diameter of the swifts give plenty, plenty of penetration, WITH some shock.

About 5 years ago, I openly wrote that I'm done with hard cast in my hadnguns

Fk hot loaded hard cast rounds, and fk the horse they road in on.

Michael you aren’t the first too mention BE-86 but it’s damn near impossible to find. That’s why I’m trying out 244, even out my G20 I’m getting mini fireball. I tried #7 but was getting mini fireball and powder residue in the barrel. When I do my rounds I will keep an eye out for BE-86.. I must of missed the story on why you don’t use hardcast bullets.

John, I'll keep my eyes peeled for a canister of be-86.

Here is a picture of a 180 grain swift. A finishing shot into the neck of this year's 55.75" rack moose from my little 357 mag trail pistol. A rutting bull moose neck and that 3/4 inch hide did not stop that bullet from drilling clear through, found against the hide on the offside. 16" of neck

Now these dmn 10mm swift a-frames, what ah treat.....

Very nice, I like this setup but it prompts a few questions.

What's the story on the front sight?

Who contoured the barrel lug like that?

What kind of sight mount is that and where did you get it? Is it specific to that particular sight or do they make several models?

Hi Jim,
Sight was filed off because it was tearing a hole in my parka pocket.
It's also more fitting with Alaskan metaphors because it's a 357 mag. So if a bear tries to shove it up my ass, it won't hurt as badly.

I reprofiled all that excessive under lug off the barrel, because it was too front heavy.

The sight is a holosun. The mount is an allchin. Sight and mount weighs 2 ounces, which is nothing.

All handgun sights nowadays, are too course. I would miss small game out at 30-40 yds, often.

We don't own rimfires, so with low velocity, fmj ammo, the handgun is the rimfire, and with swift A-frames the home defense, and bear/moose defense.

If i could do it all over, the open emitter reflex has some downsides in an outdoor environment:
When gathering firewood or thrashing brush, dust and debris would get everywhere. Sometimes, the open emitter would get obstructed.

The new aimpoint arco fixes all that:

My first red dot was an eotech holographic weapon sight gifted to me by the Eotech company in 2003. That thing did one year on my m-249 machine gun in Iraq. Never lost zero.

Then, an issued aimpoint the second tour

Third tour: brand new trijicon acog on a brand new m-4

Never had a failure of a red dot, until I mounted a burris fast fire 3 on my 357 mag.

That pos lost zero within 100 rounds of light ammo.

Go with the aimpoint......
