Thanks guys for the input. I myself have used the gameking and it passed through one deer at about 60 yards, shot another at 100 and it failed to exit but dropped the deer within 20 yards luckily because it left no blood trail. I bought the barnes TTSX last year but have not killed anything with it. maybe she can be the first to see how the 62 TTSX does.
