What 10mm ammo for bear defense (griz)

[EdP]

What are your thoughts on the Sellier and Bellot 180gr FMJ for griz defense? I would prefer to carry the same ammo I will practice with and this is available in bulk. The Underwood 10mm HC seems to be well thought of but expensive if you can get it.

200/220gr hardcast or the 190gr dangerous game load from Buffalo Bore are good choices. I like the 190s.

I'll throw my worthless 2 cents into this thread and say at least consider THIS, or something like it as this is not the only manufacture of this type of bullet.

I have no experience with this ammo for Griz defense, but all my research indicates the bullet will create a wound channel like a HP and the penetration of a HC.

Good luck,

Eddie

That's an interesting option. I don't like the idea of practicing with a 180 and then carrying a mag full of 200's with a higher recoil. Going to 150's from 180's is less of a concern.

I carry my 10mil with these up here in AK.

I use this ammo myself, 115grn version. Plenty of energy, great wound channel, and manageable recoil.

This is what I use in the 220 gr variety.

G20 with a ported barrel, practice with 40 S&W generally, switch to 10mm 180hp and to Buffalo Bore 200s or 220s, really don’t find the recoil difference to be much of an issue. Had a little woman( 5’,110 lbs) shooting it at a cc class, did fine compared with her compact 40s&w.

Springfield xdme 10mm with 3.8" or 4.5" barrel. Buffalo Bore 180, 200 or 220 grain hard cast. Or Underwood 180, 200, or 220 hard cast. Or DoubleTap 180, 200 or 220 hard cast. All of this ammo can be bought through the mail. Expensive yes but worth it. Fatrascal.

I am using the 200 grain coated hardcasts from Underwood. I resulted on it after watching a bunch of penetration testing on youtube of the 200 hardcasts vs the extreme penetrators. They both penetrated the same. I like to practice with the actual rounds I carry to ensure no failures and the extreme penetrators are almost double the price. Enough for me. Only reason I could imagine the extreme penetrators being worth it is if their muzzle jump wasn't as much or something, but considering they compensate for projectile weight by upping the velocity by several hundred fps, I doubt it. Although, I have not shot them side by side yet.

Hardcast, and practice with them.

As long as you can draw and shoot quick and accurate enough, any 10mm FMJ should work just fine.

Plenty of people have used 9mm to defend against bears.

I keep my .45acp loaded with Sellier and Bellot 230 grain FMJ, they are loaded a bit hotter than the .45acp Winchester service grade ball ammo that many consider the gold standard for that cartridge.

Any preferred hard cast brands that are most reliable in regards to feeding and ejecting? I have seen some people having issues with Underwood.

 

[HighDesertHunter]

I carry the 145 G9 Woodsman in my G20. https://g9defense.com/shop/pistol/10-mm/ But honestly, I've never shot a bear with it so...

 

[BDWMT]

I don’t know if there is a factory option but I’m loading the Swift A-Frame 180s. Seems like the only true hunting bullet option.

Underwood Xtreme Penetrators, 140gr.

They also have a 150gr Xtreme Hunter that looks in-between Penetrator and Defender. In terms of the flutes.

I wanna say there's footage on Kentucky Ballistics YT channel of a 10mm Xtreme plowing thru a very impressive distance completely thru whatever ridiculous amount of Ballistics Gel that was. And what's cool about the vid.. is he does thesame shot with many of the boomers people tend to think of for Grizz.. so it's a great vid to help you Visualize the energy levels of those catridges in comparison to one another. Because we're all gonna be familiar with at least one of the cartridges, like the 10mm.. so THEN... when you see some of the impressive boomers like the 500sw and the 460sw do there thing, you a) develop a newfound respect for the 10mm, and b) are dumb struck by how damn much more power you can obviously see at work with the big mamma-jamma rounds doing their thing. .454 Casull is in there. .50AE I think. And of course .44Mag too.

Underwood 200 hardcast alternated with xtreme penetrators it is a solid combo and works

Test options in your gun, see where they hit and how they feed.

The easy answer has been the 190gr Buffalo Bore mono-metal bullet in my experience. They have fed and shot well in 3 different 10mm's. No failures to feed, hit to the same point of aim as 180gr FMJ practice ammo. They are expensive.

The Underwood 200gr hardcast only fed perfect in one of the 3 10mm's after extended practice. My Sig 220 Hunter shoots them great, the G20 and Sig 1911 had failures. The 220 Hunter probably has stouter springs, it's the only one that fails with 170gr light practice loads.

The Underwood 140gr Extreme Penetrators hit 4-6" high in my 1911 and G20 compared to the 180gr or heavier loads. I ruled them out for me just because of this. If my guns shot them closer to the sights point of aim, I'd not worry about their performance. I never tried them in the 220 because the 200gr hardcast gave me no reason to.

Hope that helps. I like to start by slowly shooting paper to see point of impact and checking how the ammo feeds. If it passes that test, then I'll try shooting faster and from simulated field conditions to see if improper form/grip makes the gun jam. Once I'm confident in the gun/ammo combo, I'll go back to cheaper ammo and practice drawing and firing a lot. My 220 is a very heavy gun, but I keep taking it because I trust it the most and don't want to start my whole process over with a lighter gun.

The Underwood 200gr shoot really good and 100% reliable in my Glock 29 with KKM barrel!
