My hunting buddy's daughter has used 70 grains T7 with a 240 grain XTP for at least the past 7 years. She's taken at least 5 deer in that time. The only time we had to track the deer and finish it off, the shot placement was off- bullet hit too far forward, took out 1 shoulder and part of 1 lung but missed everything else. Every other time with good shot placement the deer went down fast...
