Interested in hearing opinions here on bullet choice for some big Russian boars using S&W 500 mag. Of course the pistol has more than enough power to get the job done, but the choice still remains, choosing a lighter ~350 grain hard cast or jacketed bullet cooking along at high velocity or choosing a heavy, ~600-700 grain hard cast lead bullet at lower velocity. It's the old penetration vs expansion debate I suppose. I prefer headshots with rifle, but will likely opt for heart/lung placement with the pistol. It's probably splitting hairs I suppose, but I'd like to hear what others folks here have to say about it.
