[QUOTE="orangeride, post: 490116, member: 19863"] My barrel is 1-7.7". I finally got my crono working and did some primer testing. My 69 SMK load is 24.5 gr varget, lapua brass and Rem 7.5 primers. With unsorted brass and bullets, I had an average extreme velocity spread of 43 FPS per 5 round group shot. I then sorted the bullets and brass and that got me down to 20 FPS. The funny thing was the best group I shot that day, was one where the velocity spread was closer to the 43. I have rounds loaded with Fed and Cci match primers, but I've been waiting for a day for the wind to let off. I'll post with my results after I test the other primers. I would assume in the end the load with the most consistent velocity will be most accurate. [/QUOTE]
