[QUOTE="OhYtD, post: 1655408, member: 107977"] I have heard several different reasons offered that could be behind this phenomenon...one thing I can say for certain...I have absolutely seen it and I was confounded. Many moons ago I barreled up one of the first rifles I ever did. It was an absolute tack driver. It was just a 308 on a 700 with a trigger, an H.S. Precision stock and some glass bedding. I was shooting reloaded Lake City 58 brass and it was pretty well hardened up after 32 years...at that time one of my buddies had been messing around with a chronograph. This rifle would put every shot touching at 100 yards off a bench, but ES was well in the 50-60's, sometimes higher. I accidentally stumbled onto some info in a reloading book about annealing brass cases and tried it. Next trip to the range the rifle shoot single digits and my buddy was going crazy...we concluded that the only thing I did different was anneal the cases. They sized easy and the bullets felt like a feather compared to seating before, problem was the group opened up to like 1 1/2" or so. I don't know, but I think some powders must like the bullet to be seated tightly. Which these were...the expander ball actually chirped and the handle had to be bumped pretty good when the case was withdrawn from the size die. [/QUOTE]
