[QUOTE="Quickshot, post: 1339269, member: 102444"] Hi Alan, I agree that modern analytical balances have solved the issue of inconsistent charge weight. I trickle to +/- 0.5 kernel; just because it's fast and easy. Brass prep was the key to low Es and Sd. It is still critical to tune the load and seating to match the barrel harmonics. A well tuned load will hold the sweet spot better over environmental and charge weight variations. But, it is possible for BC variation to spoil a well tuned load. I've had 1 out of ten bullets leave the muzzle with in 3 FPS of the other 9 and by 55 yards it's lost 30 FPS more than the other 9. Those rouge rounds always impact way low. The deviant POI is easy to spot at 2000+'yards. I have started culling rounds with a concentricity gauge. Cheers, [/QUOTE]
