While I hven't used them, a few of my buds do, and without problems. From what I have seen, BT's perform well at handgun velocities. Also I would use the 140 gr. for deeper penetration if needed. Don't worry it will open up, yet hold up better if you need to go through bone. I will be loading the 120 gr. , 6.5 cal. in the 260 Striker for my son this season. I tested 165's for the 30-40AI 15" Encore, but it like the 165 gr Scirocco's better.
Well , those are my thoughts :wink:
