Glock 10mm bear loads

The argument that a 200 grain had similar velocity and energy as a 300 grain from a larger cartridge doesn't account for a big difference in the momentum of the heavier slug. I hunt with a .454 Casull and my previous hunting handgun was a .44 mag. I shot a 600+ lb. black bear twice in the chest with it. Found both bullets under the hide in the back of the far side hind quarter. But he didn't drop at the first shot. If he were attacking he would have chewed me up in the time he would have still been up. A forest service report I read suggested the .458 Win mag and 500 grain soft points as the most reliable to stop a griz right now. I've hunted in Alaska and been close to grizzlies, they dwarf black bears. I stood one down armed with my .44 and a can of bear spray and seriously feared for my life. That .44 felt like a toy. For me, I'll be carrying a .44 or bigger double action in a chest holster loaded with a stout hollow point for maximum damage with the one or two shots a guy might get off.

Here is a story I recently read.

I have to correct my last statement. I mentioned that I use double tap 220gr. in my Glock G 40 MOS ( This is not a 40 Cal) but a 10 MM DT 230 Gr. for those that may have thought differently. !6 round MAG filled with the following pills. Oh...If you want to stop big bears and your secondary weapon is a hand gun keep in mind, don't concern yourself with doing tissue damage these bruins have plenty of that, rather concentrate on braking bones. Hard cast is the only way to go.. Best of luck!

I carry a gen 4 Glock 20 with hi viz sights and a stainless KKM barrel. I Reload a 200gr wfn-GC with 800x. This is my defense load while hiking/hunting in black bear country

I can't figure out if you are using for hunting or defense. If it's defense you will be facing Grizz in Wyoming. Do you really think 10mm is enough medicine for a Grizz? I would not want to be the one to test this.

Going to try the Buffalo Bore 220 gr in my Glock. next yr going to Wyoming and will be packing it. Looking for a respectable handload since I have not reloaded in awhile. Do the 10mm Glock prefer any brass brand over another ? Thank you. Ed

Check out exterior ballistics as there are MANY factory loads that are pretty weak, but only a few that are full house. Sig Sauer makes 180 gn bullet loads (FMJ and JHP) that shoot the same velocity (1250 fps and energy. Best deal I've found to shoot in my G40 MOS. Also check out Recoil Rebound spring/guide rod for felt recoil reduction and less stress on your Glock frame.

Sorry velocity is right; energy about 650 ftlbs

When did everyone decide that the 10mm was a "big" chambering? I'm a big fan of the 10mm, but it's just a small step up from a 357 Mag and well behind even the 41 Mag.

If you're looking for a backup against bears you'd be better off practicing more with a rifle. The "volley fire" approach to self defense shooting has always been the angle that 10mm advocates take and seems contrary to the core focus of this sight.

I'd say it's been in the last 5-10 years or so, with more stories of Alaskans using the 10mm as a sidearm being shown in the spotlight.

That being said, the core focus of this site is long range hunting. The topic of this thread is bear defense. The 10mm has been proven effective in this situation, and "volley fire" is about what anybody can expect, and hope for, in a rushed, defensive situation with a bear.

Go to the Sierra manual. Or call 'm. Good folks to work with. HTH!

I've always viewed the 10mm as the 6.5 Creedmoor of handguns; it's a great chambering, but there's a lot of unrealistic hype out there. A 10mm will never be a 41 Mag, and will never be a "stopping" caliber. It's a good choice for folks who want to run factory ammo and want reasonable recoil.

Everyone just needs to be sure to test the actual performance of some of the heavy bullet ammo that's out there before getting too excited. Meplat matters at handgun velocities.

You have a point, undoubtedly, about the meplat at handgun velocities. People need something that they can actually control in a situation like a bear attack, and the 10mm seems to fit the bill for that quite nicely. Much better to have the capability to volley fire, per your post above, with a "capable" (not hot rod) cartridge, versus one or two shots with a big bore revolver. Using a handgun against a large bear is always a losing proposition, but if it's going to happen, it should be with something you can control/manipulate, which for most people, is a semi-auto with minimal recoil.

As far as I know WY G&F do not recognize the 10mm as a hunting round but does state a 500 foot pound at hundred yards retirement.
You can easily get there with 6" barrel and 200 grainers but tricky with a 5" barrel. I just verly get there with 200 grainers and longshot powder.
Can not help with a Glock question as I own everything buta Glock

what is your load for longshot?

If it were my hide, I'd either carry a S & W in .460 or a Ruger .454 Casall.
