[QUOTE="CMP70306, post: 1988844, member: 36999"] So did some testing with Superformance in the 6.5 PRC, went from 57.6gr up to 61.8g and velocity went from 3153 to 3420 with some light extractor marks and a heavier bolt lift. I'll be giving the 61.2 to 61.5 window a test as the velocity spread was only 3396 to 3402. The whole group was roughly 1.5 MOA but the first 4 were low while the remaining 11 went sub 3/4 MOA. I also did more testing with StaBall 6.5, did the same load as last week but the groups opened to 1 MOA instead of sub 1/2 MOA. The weird thing is that the velocities seem to split between 3320 and 3360 with an odd 11 o'clock string even though they are all 59.3gr. I have the Lee FCD on order so I will have to try that and see if it helps tames the odd results I seem to be getting with StaBall. Also I've been updating the document so if anybody else wants to add their load data please feel free.
