I've killed with 64gr Power Points, 75gr Swifts and 62gr TSX. Haven't had a bad experience with any of them, the only one I've ever recovered in a deer was the PP and it was a RCH from making it all the way through. It weighed 57grs.
Have seen deer killed with 53 and 70gr TSX also.
The 62gr TSX is generally what I stick with and I do drill shoulders.
20 years ago we had Johnny Cash, Bob Hope and Steve Jobs. Now we have no Cash, no Hope and no Jobs. Please God, don't take Kevin Bacon.
