Thanks for the data. I have PD 124gr JHP's on order. I tried 5.8 PP , 1.16, 124gr PD Fmj's, the other day, it was the most accurate load I tried with the CZ75, the Glock 19 didn't like it at all, most accurate in the Glock was 4.3gr's BE 1.15, 124 PD fmj, and of course the CZ didn't like that very well. 5.8 -6gr's of PP really lets you know it! Definitely louder, more recoil, I can only imagine what a full 6.6gr charge would be like.
