Both those and the 250 Matt's (that I sent you) did fine with 7 gr of Power pistol. 705 FPS and dead on. Either way I have the crimson trace laser grips on it now.
Well I shot it for the first time. The 165 flex tip at 750 fps (critical defense) from Hornady shot about a foot low if not more at about 17 yards. I also tried some 200 grain cast of 200 grain xtps with 7.5 grains of unique that load was okay and I still a little bit low. That said at 800 ft...
