Jerry mentions that he was using 45 gr, beyond the max published of 42 gr. Maybe that's why he got higher velocities.
I also have had very good results with 100 gr Hornady BTSP bullets as well as the 95 gr SSTs. The most accurate load in my rifle used Hunter powder, although a few other powders like W-780 and RL-22 worked fairly well also. I don't have my load log with me right now, but it was a bit below Ramshot's max load.
