[QUOTE="Bart B, post: 794712, member: 5302"] My best experience with exact charge weights versus metered ones that have a 3/10ths grain spread was back in '91 when working with a few others developing loads for a new Sierra match bullet for the .308 Win. round. We ended up choosing IMR4895 as metered charges with a 3/10ths grain spread produced the best accuracy. Several thousand rounds were loaded with new Winchester cases and Fed. 210M primers. 20 rounds picked at random shot into 2.7 inches t 600 yards. In a couple dozen or so different barrels, that load shot no worse than 1/2 MOA at 600 yards based on 15+ shots per group. In a test with exact charge weights, the accuracy was no better. Which means to me, if the right powder's selected for a given bullet, it doesn' matter to much how precise the charge weight is. [/QUOTE]
