[QUOTE="CB11WYO, post: 976340, member: 57339"] Well for question #1... I trim to .010" under the "max case length." So if your 30/06 shows a max of 3.494" I would would trim to 3.484" and so on... :) As to the effect on accuracy... I've never tested that specifically. I do know that after 2-3 firings of typical cartridges (22-250, 7mmRM) I only see a measured difference of .005" or less between cases when taking a sample of 20% of my cases. In other words after firing 2-3 times my brass all measure within .003-.005" of each other. That spread is even less with brass from, say my 20 BR. Would be interesting to know of the accuracy implications though... -Clint [/QUOTE]
