[QUOTE="timotheius, post: 1502157, member: 66591"] Thanks for your input. The reason I went as high as 61.6 grains of H4831 is because I was trying to get to 3100 fps. 61.6 got me to 3060 fps according to my magnetospeed. (24.4 inch barrel, 1-10" twist) That charge grouped well at first, and pretty much filled up the whole case with powder. Anything more would have been a compressed load with the H4831. However, I will back the charge down some and see where that gets me. I guess if I had to choose, I would much prefer MOA accuacy over an extra 50 fps in velocity. And you are right about the brass, after 4 firings several pieces of the brass developed a uniform crack around the case body about 1/4 inch above the case head. [/QUOTE]
