I just loaded some 158 grain XTP's and some 158 grain A-Frames. I loaded both with 16.1 grains of H-110. I loaded 12 rounds of each. I only had time to try both in my 9" MGM Encore before I got called away. I fired two 3-shot groups with both loads. Using a red dot the XTP's 3- shot groups were 1", and slightly over 1". The A-frames were just over 2" for both groups.
I will try both in my 6" Security Six next outing, and also chronograph out of both guns. As of now, I plan to use the XTP's for deer this fall.
