Would you feel under gunned tracking a big (400 lb) hog with a 315 grn wide flat nosed lead bullet pushed to 800-850 fps, a little higher than a typical .45 Colt hunting load?
I see many hog hunters prefer a magnum with this type of bullet and weight. But a .45 Colt seemed pretty good at killing stuff, so one with a heavier bullet and a little extra oomph seems stellar to me...
