[QUOTE="Vomact, post: 1044998, member: 85311"] Thanks guys! I had already measured some loaded factory ammo (at .251) so I have .258,259, 250 and .251 bushings. I used a K&M neck turner and just took off the high spots. I use RCBS Gold Medal dies (without the expander ball) when first prepping new cases. From then on I use Wilson dies. I am using two different types of brass. I went for my brains and bought 100 Lapua (that stuff is HARD). I did a weight analysis and the case weights were very uniform. The weight variation on the box was practically a straight line. I purchased 50 rounds of Norma in a 'what the heck' mood an these are TOTALLY different. The weight distribution is a straight sloped line, not a flat line or a normal distribution that I would have expected. At first I though the scale was drifting so I weighed them again. Sme results. Same results with the balance beam. Any Ideas why this happens. Thanks, Vomact [/QUOTE]
