Core-Lokt's get'er done.
I've put 150 and 170 grain .30-30 core lokts into deer from about every angle and never had one come apart. The only ones I ever recovered were 170 grain from lengthwise shots and they were near picture perfect mushrooms after penetrating nearly full length. I busted both shoulders more than once with 170 silvertips and core lokts and never recovered one.
