[QUOTE="britz, post: 188208, member: 7865"] I wasn't sure if you were refering to standard deveation in velocity or distance from aim point (should have guessed that you were talking about velocity though). I agree with the above posts that you should let the gun cool between shots. Also, I have noticed a significant difference in velocities from a bad batch of primers. I had about 25 cases primed with some mag primers and decided to fire the primers and resize the cases inorder to use those brass for a test using CCI BR2 primers in my mag. I fired the brass into a bundle of old ripped bluejeans. I was shocked to hear the poof on some and a bang on others and a crack on some. I guess my primers were old and exposed to some bad stuff. I had been disgusted with the results of my chrono tests last summer using that load and I think I know why the SD was so large now! I am only going to use fresh primers from now on. [/QUOTE]
