Nate, the TTSX in the 62 grain will go thru both shoulders at 50 yards on a 150-160 pound buck, I have not had one so shot go more than 25-maybe 40 yards. Try the 62 TTSX no need for the 70, I would recommend a lighter TSX bullet like Ingwe shoots but have no personal experience with it. Shoot one or both shoulders, solid copper, your good to go. The 75 grain Scirroco is stopped by a dead deer, so I have no further use for that one, I am going to experiment with the 62 grain fusion if I get a chance on a third deer (doe)this year. Finally the blood trail is not that great nickel size exit hole, that is the only drawback.
