Well My TC has a tendency to really like the hotter side of charges. I tried from 100gr BH up to 130. The groups started on the lower side charges at around 8 inches and tightened up to 6 inches at around 120 grains then opened up a smidge to around 6.5 to 7 at 130. Prior to my switchover to BH I usually shot around the same charge weight with T7. But as I said, she likes it hot. I really wish I could find a bullet that I could back off to around 90 grains with her. Even with all that recoil reduction stuff in the stock it has a wollup to me poor old shoulder on the bench. It's negligible off hand but bench postitions just crack me up. Getting to where it even bothers me when I shoot left handed with the shoulder that's not been hurt as often.
