Grizzly ammo recommendations

[Patriot2]

I have been shooting 200 grain hard cast and 180 FMJ from a new Springfield XDM Elite 10mm and they are cycling fine.

I literally went with the Grizzly Big Bore Ammunition cartridge company. Flat nosed hard cast bullet with a Grizzly paw print on the top of bullet nose

Hard cast has always cycled well out of my Glock 10mm full size.
I did notice that it shoots high as close yardages 4-5 inches high.

To me, it seems Underwood shoots better than Buffalo Bore but that's just my experience.

Been a while since I read it but supposedly the early gen S&W 10 mm had issues with loose fitting mag's causing jams and the mag's falling out.

I've heard the same but have no personal experience with them.

You could try the copper jacketed ammo. I had some FTF's with 9mm in a SW Shield and going to the copper jacketed stuff solved it.

FWIW, My Stock G20 has been 100% with 700rds of that Underwood and Double Tap 200g hard cast ammo and that was before the cherry coating lube.

It's only when you go to the after market barrels with tighter chambers that you start to see problems with the Glocks. Stock, they just plain work.

We ended up getting heavy recoil springs and magazine springs. Changed everything and have shot two mag each no jams no mag drops or anything.

10mm 140gr Underwood xtreme penetrator for me.

I run solid copper bullets in my 10mm. The hardcast lead shot well but I didn’t care for the puff of atomized lead smoke from the uncoated bullets.

We’ve had a lot of bear encounters at night and I didn’t want to risk not being able to shine a light through it.

Those underwood hardcasts functioned well in my factory G40 as well.

I wouldn't overthink it. Get something that functions reliably first. I'd use flat nosed FMJs if thats what cycled reliably. Hopefully you've shot those pistols before now and have something they cycle reliably?

Edit to share: Cool story i heard covered on @bearcreekbandit's podcast. In relation to this thread, they used a hodgepodge of assorted 10mm ammo to stop this bear.

These Alaskans Stopped a Charging Grizzly at 5 Yards with Their 10mm Pistols

Two alaskan hunters scouting for moose were charged by a massive grizzly. Using their G20 pistols, they stopped it at just 5 yards.

I’m picking up my G40 tomorrow and have been curious about the underwood hardcasts, which ones specifically did you have success with? Will be primarily for bear defense in the Smoky mountains in late December

Everyone wasting time

.50 cal

440 grain Corbon full metal jacket only thing that will stop grizz in their tracks. One shot one kill in skull

Otherwise you are using child’s “sling shot”

Remember - you get one trigger pull when momma is running after you because you are between her and Cubs

Think about that one for 5 seconds because that’s all the time you got

Ha!

I have spent a lot of time shooting my G20. I ran more $$$ in Hardcast ammo through my stock pistol than I paid for the gun itself.

Mine is 100% with that 200g Double Tap and Underwood HC....and no tumbling that some report with the heavier bullets.

It's critical to get out and test these bear defense weapons. My Shield 9mm was choking on the Buffalo Bore Hard cast...but it functions fine with the copper jacketed stuff. My G19 functions with everything.

Glock knows reliability. The guys messing with them; Rebarreling, changing springs etc are just asking for trouble and I've seen a few that had to go to an armorer multiple times to get those modded pistols to be reliable.

I was curious as to what my G20 would do penetration wise and shot it through some scrap lumber. I had a total of 6" together and never did get it to stop a bullet.

IMO, Muzzle energy is only part of the equation in stopping these bears. A magnum caliber is not going to knock a big bear off his feet. Heck, we have all seen big critters can take a powerful rifle bullet like it was nothing. The bullet shock does not affect them like a human.

The over penetrating ammo like the hard cast will punch through a skull or heavy bone...or penetrate the length of the critter breaking whatever bones are in its way.

After seeing some of those breathtakingly big VW Bugs with fur on the AK islands at close range, I'm convinced this is what we need in these encounters.
