[QUOTE="ruby76, post: 1456718, member: 95995"] Initial results are in. Prior to these tests I have only 24 rounds through this barrel for break-in. I used R-P stamped brass formed and prepped by me, Federal 215 primers and RL17 for all shots below. I'll have to re-do these tests as I was having some issues with my magnetospeed. 59 grains read 2694 fps 60 - 2722 61 - 2745 I can say however that at 60 grains I could see an extremely faint extractor mark, 61 was more visible and slight primer cratering. My 62 grain shot had slighly more of an extractor mark (not even shiny and highly visible), same slight cratering but did not register speed. I'll load again at half grain increments starting at 58 grains and go from there. I'll be testing superformace next. [/QUOTE]
