I am wanting to load up some 165 gr .40 Berry's FP bullets using some winchester autocomp i have. According to the load data on Hogdon's site, the starting load should be 6.3 grains and max is 7.0. I am using a progressive loadmaster and according to their auto-disk measuring instructions, I am using the disk and hole that should provide 6.2 grains but i am consistently getting 6.5 or 6.6 grains. If I go down a size, I get 6 grains. 6.6 is mid-way between starting and maximum. Thoughts on whether that will be OK in a glock handgun?
Also, would Clays be a better choice for berry's?
