"I have a .45-70 GS and want to know if it is a good gun to take hog hunting." OMG, I think you know the answer to that, from reading other posts. Can other calibers do the job? U bet. But, you're talkin about a supreme hog taker here! If you have it, use it. It will put a smile on your face. Go for it, buddy. You'll not be sorry!
