I neck size only for years. Bolt action 308, fired formed cases hold the shape of the chamber. I also mark the cases with a marker to load into the die & chamber at the same position, which maybe overkill, just to keep everything consistent, I'm now trying partial neck sizing 1/8 down from the neck, my thinking is the case should be as close to the chamber for maximum accuracy, as long as the case can eject. Using RCBS neck die, nothing fancy. Just take your time,use the same make brass, some brass is thicker than others. uniform primer pockets, deburr flash hole, check case size, chamfer inside & out. Also try different primers & seat to bottom of pocket. It's fun to reload, trying to get the round as accurate as possible. Hope I helped in some way. Be safe Chris
