170 Sierra FP hammers em well enough.
^^ What he said! I've been using those in .30-30 and .303 Savage loads for years and no deer has gone very far after being hit.
Before that (1970's) I used regular ol' Federal Power Shok factory loads and they worked perfectly on deer in the brush I hunted in.
The hog hammers should absolutely kill just as well. Who knows, They might even make deer mo' deader.
