[QUOTE="lejuch, post: 2182349, member: 95250"] Unfortunately, I do not understand the velocity difference either. Regardless of the powder I have used, once I get to just short of 3200 I begin to experience stiff bolt lift and ejector impression/swipes. Cleaned barrel numerous times, brass sized only .001 to allow insertion into chamber, etc. I get great groups at that speed but the moment I get to roughly 3200, regardless of powder, overpressure signs begin. 22” barrel is the culprit of some of the velocity loss, but doesn’t explain all of it away. I may try different primers when I’m able, but currently only possess 215M which logic says those will INCREASE pressures. [/QUOTE]
