DVD: I'm not a big and slow person either. Used the 45/70 and old 405 Silver tips on game in Africa and didn't do well. Another guy a few years back used it with CoreBon ammo, which was hotter and better bullets, and it worked well. I personally want a bullet to be moving in excess of 2800 fps if possible. Read a good article on impact velocity and it's effect on game (5000 animals shot), and the general concensus was that a bullet going that velocity, did a lot more damage. In fact the finding was a bullet at 2700-2800 fps, created a blood back flow through arteries and veins, that cause the animals brain to look like it had a stroke.
But, we're also talking ability to penetrate on a raking shot (left hip to right shoulder on a big elk, fi:) that's a lot of penetration. I shot a Warthog the size of your pig, in RSA last year, and used the Nosler ballistic tip, in 150gr from a 308, and did a side to side shoot through, so not hard on a hog.
