Haskins02,

I just realized we've omitted to discuss the other side of the equation. The primers don't all have the same tolerance, either. I really like the Russian primers (Wolf and TulAmmo) for performance consistency, but they are distinctly more difficult to seat than a Federal or Winchester primer or even than some CCI primers (which used to be the hard ones to seat before they revised their cup forming method). I don't know what primers you are using, but it can have an effect.

As to other tools, on the K&M tool you can unscrew the head until you maximize the ram leverage at the end of the priming stroke. But I'm surprised the Lee is giving you grief. If you want the easiest slip fit into a primer pocket, the Wilson case trimmer and their primer pocket profile cutting tool will give you that, but it's slow work if you have many hundreds of cases.

Lapua does make a small primer pocket version of the .308 case, but that kind of size difference is pretty obvious.
