I just bought a new .450 Marlin for hog hunting and was wondering if anybody had any experience w/ them for hog hunting. We've used a variety of guns for hog hunting but it seems like you need a large caliber bullet to penetrate the shield on a large boar so you can get a good blood trail. If you shot them w/ a smaller bullet the wound seems to close up and seals off the blood. The 300 grain bullet should leave a very large hole.
