[QUOTE="dmax1800, post: 914699, member: 68255"] That is exactly the problem. I had been running the drill for several revolutions and calling it good. On the few pockets that I measured after running the uniformer, they were probably deep enough. I rechecked a few and found some at .130 and some at .126. After running the uniformer and cleaning it several times, the .126 pockets came up to .130. When I seated the primers in the pockets with .130, I was able to get them recessed by .001 to .002 and the case did not stretch: they stayed at 1.900, which was my trim length. I also tried a Lee and RCBS shell holder. The Lee is apparently a little sloppy and does not give the support of the RCBS. It was easier to get the primer seated with the RCBS than with the Lee. Side note. SAAMI spec for LR is .125 min and .132 max. At the minimum it would be hard to seat the primer flush or slightly recessed without starting to crush the primer. Thanks guys for all your input. I don't think I could have figured this out without your help. [/QUOTE]
