gnappi-nice score! I love those grips-I’ve got Ajax fake ivories and have bought two sets of wood rugers so far that don’t fit well.
I haven’t been able to find any BP, but from what I’ve read since getting mine I chose to go with T7. The ROA for me will not be a target gun, but may be used for javelina hunting and seems to be doing great with a 35gr (volume) charge, which is energy equivalent to 40.2 of BP, under .457 balls and a lubed wad.
Hits on with fully lowered rear sight at 70yds for me so I’m not gonna mess with it.
I’ll grab BP when I can find it, because it will be more cost effective for practice and jackrabbits.
