Sometimes I wonder if buying a cocentricity gauge was such a great idea, being blissfully unaware has its merits! My question relates to a problem I'm having seating light (therefore short)flat base bullets straight in my 6mm Rem. Using normal RCBS FL dies I can get fairly straight cases (less than .003 runout). The problem comes when I seat the 68 gr. hollowpoints, which need to be seated less than one caliber deep to get anywhere even remotely close to the lands. (I'm 60/1000 off at this depth)I seem to get decent accuracy anyway but it bugs the you know what out of me! About 50% of the loaded rounds have 5 - 12/1000 runout. I've tried rotating the shell while seating, I polish & clean my brass, I chamfer the cases carefully etc. Is it the shallow seating that's causing the trouble (short bearing surface)? Would benchrest dies such as Forester's help? ANY advice would be most appreciated!!
