I'll be going on a pig hunt soon with a bunch of my friends. Alot of calibers will be represented including a .44 AutoMag. I picked up a Savage M99 in .300Savage at an estate sale a few months ago. It shoots fantastic. This is what I'll be taking on the trip.
I can't give you any advice on hunting hogs as I've never had the chance to hunt any.
I can tell you this, the Savage 99 in 300 Savage is a sweet rifle/caliber combination.
I had one and sure took a lot of deer with it, I wish I had mine back.
