308 enough for brown/polar bear?

Very true, I have seen the same thing, only caveat is I have seen every duck gun I have hunted with or around fail to fire or get a jammed shell that won't extract at some point pumps just as often as semiautomatic. Only failure my browning has had was bad ammo-probably got wet. I have even short stroked my ol 870.

I have had more failures in my 870 than my stoeger m3k. The 870 Will occasionally decide it doesn't want to eject, period, and the only recourse is to spike it into the ground. Meaning, grab the slide with both hands and slam the shotgun butt first, barrel straight up, on the ground. That will break it loose and eject the shell. No clue why this happens. My stoeger has only jammed when I've put low quality ammo in it. I wouldn't trust either for a dangerous game backup though. If you don't hold an inertia shotgun tight to your shoulder it will short stroke, and that's a major problem if you're in a defensive situation

I would be interested, if you try them, to know how well they shoot. He switched to Speer and we lost touch with each other.

I loaded up heavily on the speers, so unless I stumble across someone willing to send me 10 interlocks for testing purposes I probably won't have to buy bullets for this gun for a while. Unless of course terminal performance in the speers is sub par. Then I may resume the search. I do have 260 accubonds that shoot well, albeit a bit slow, so those are a solid second choice for me.

I would use 8.6 blackout for black bear, but considering this thread is for brown and polar bear, those are much bigger game. 8.6 blackout in supersonic is devastating. Even in subsonic it's devastating if one can get close enough.

I do use 308 and like it, but it wouldn't be my first choice for brown or polar bears.

I've been researching 458 socom 350gr to 500gr hard cast in the AR15 platform the last week. It's ballistics are similar to 45/70.

Tromix and Wilson Combat make AR15's in multiple barrel lengths chambered for 458 socom.

11 rounds of 458 S in a lightweight semi-auto.

On Buffalobore's website the owner of BB posted how he has successfully used 458 socom to take down large game over 2,000lb pounds. Over 5 feet of penetration. They never recovered a bullet despite the angle of the animal.

A huge step up from a 308, and in the smaller/lighter AR15 platform rather than the AR10
