Grizzly ammo recommendations

[Andrewlonghi]

So after doing some reading and watching several you tube videos on which ammo to get for bear defense and ended up Purchasing 6 boxes of underwood HC 200gr. Well fast forward to yesterday we decided to shoot a mag each and disaster struck. We had jam after jam in all 3 and a mag drop twice. So we scoured the internet for solutions and ended up ordering some new guide rods with 24lb springs and new spring for the mags.

My question is what ammo would yall go with in case this doesn’t fix are problems. I was looking at Hornady back country. Getting down to the wire for us before we leave

What pistol are you shooting? I have heard glock and springfield doesn't like hard cast ammo much. I ordered 4 boxes of double tap hard cast and after hearing that I bought 4 boxes of honey badger solid copper. They are a lighter bullet but have heard good reviews

M&P 10mm

Could try a solid copper instead of hard cast

Any reliable ammo from any reliable gun will probably dissuade a grizzly from continuing to try to chomp on you.

That being said, I carry a 44 magnum revolver loaded with all copper hunting rounds so no worries about jams, or the gun going out of battery if things get too up close and personal.

Buffalo Bore and don't go to max loads if it is causing cycle issues.
CNS hit up close.

Im shooting the same ammo from a Springfield XDM Elite and have not had any issues.
I hope the guide rod solves your problem.

I’ve practiced with and had no issues with the Hornady Backcountry Defense 9mm ammo for this year so far. That’s what I’ll be carrying for archery season here in Montana. Definitely a good idea to run a few mags of whatever you decide on though to make sure it runs better than the Underwood in your gun.

Don't mess with the springs, go with a good barrier blind ammo like Hornady Critical Defense, Critical Duty, Federal HST, etc.. It's about rounds on target and reliability.

IMO, 10mm are great for grizzly ammo. Most high-end 10mm ammo manufacturers list their 200 grain HC loads as having greater energy than their 220 gr. I personally have seen better performance with the 200's and don't use the 220's at all.

I've used that stuff for years.

Glock 40 with a 26# spring and LW rod.
Also the 45 Supers in my FN 45 TAC

I just ordered some 150 extreme hunters for the 10mm. I was running low on hardcasts. Also realized how stupid it was not to carry a spare mag.

Underwood is definitely where it's at. Supper hot and cheaper than buffalo bore. None of that 40 pressure crap the main manufactures sell.

Not so sure about the Springfields. I’ve used the Underwood 200 and 220 HC in two Springfield XDM’s, compact and full size, with no issues.

When using hot loads the slide velocity can have negative effects, as can the increase in recoil.
I have not made any mods to a M&P, but made several mods to shoot 45 Super out a 1911. The actions/reactions have to be balanced. Even with recoil springs that would be good, a limp wrist will cause jams easily.
