+1 on everything Packin said. I've also had a hog take a 308 to the vitals and pop up like a carnival target. One of the weirdest things I've ever seen.From a capacity for soaking up damage perspective...I've seen them take 3.5" 000 buck and charge, 308's in the boiler room flop over and then get back up and take a run at you. It just depends on how pissed off they are. I've had plenty I've dropped with 300 blackout, 7mm-08, 308, muzzle loader, 9mm, 10mm etc. It is really variable even with good shot placement. About 1 in 20 tries to take a run at me.
Looking into a hog hunt for this fall . From everything I have seen the range at which they are shot screams muzzleloader. The question I have is what bullet will hold together and have good penetration ?
