Got to try out 6.5gr of Titegroup today, eeked out an average of 1990 fps in the ten rounds I loaded up. Primers were just beginning to show signs of pressure. Will definitely be working up with Autocomp, I appreciate the advice! I think I'm also going to try BE86 as it's been a dandy for light...
At the risk of necroposting, I too suffered the same dilemma. Out of my 4.25" bbl, 6.0gr of titegroup averaged me 1830 FPS. No pressure signs and they cycled well. Hoping to work with a few other powders and get it into the 2150-2200 FPS arena.
