U need a 12 gauge automatic shotgun with 1 1/4 oz. slugs period.
The 45-70 is popular but it only brings 3032 muzzle energy so it's not what I'm looking for.
Somebody wants a dead hog.
An inexpensive gun that will do the job is an sks, but it is the lowly 7.62x39.
Yea I had a 300 weatherby mag once. Dam thing would rattle your teeth so much recoil. I traded it. And I love 45/70 so if I say the recoil was too much then I'm being serious. It was in a light synthetic stock I'll admit which didn't help.
Real life beats paper test hands down!!! I thought about the 300blk but went with 7.62x39 and 6.8 for ar platform, now once my cans come in from NFA lock down I might go for 300 blk, but you just can't beat the price of 7.62x39, and I have had great luck with steel cased soft points, I got some steel cased 7.62x39 hornady sst, waiting to see how they work
