[QUOTE="M Jager, post: 921949, member: 5753"] bootsking- we tried a couple different things. First we tried a bullet test, all shoot essentially the same. Then I shot groups while bumping up powder charges in .5 grain steps, then took what seamed like the best charge weights and started playing with seating depth. Again everything was pretty consistent across the board. I threw all charges on my Harrell then weighted them, throwing anything that wasn't spot on for weight back in the can so my powder is both spot on for weight and volume. I didn't ask my friend what his methods were. He has a lot more accurate rifles than I do and knows more about loading than I do so I believe his techniques are sound. I don't use quick load so C Long OBT is somewhat Greek to me. Westcliff- I think we can rule out primer seating. But my friend and I unify our pockets. I think that its very unlikely that we are getting inconsistent primer depth in these cases but none of our other rifles. My friend shoots benchrest and is pretty anal about these things. Firing pin protrusion - I don't know and don't know off hand how to check. Fired primers look normal but that's not very scientific. Headspace is set tight. Sized/new cases chamber with slight bolt resistance. I am slightly under a go gauge and am definitely not long. I am going to smoke some cases and take some measurements tomorrow. Everything I read seams to indicate that you can't be too tight but I am wondering if that is not the case. I have used CCI 400 and 450 primers depending on powder. Friend mostly likely used BR4s or Feds, I didn't ask [/QUOTE]
