I want to try pig hunting pig with a hand gun , I have 2 possible guns . first is a 357. maximum contender - 170 grain bullet at 1800fps or a ruger .45 colt shooting a 260 grain bullet at about 1200 fps. The contender is the more accurate of the two of course . witch is the better choice? I have a good spot were I should be able to keep the shots inside of 75 yards easy.
