Re: Question about Lee case trimmer
I was able to contact Lee tech support through their website... don't know how I missed it when I first looked. Anyway, here is their response to my question -
The SAAMI (Sporting Arms and Ammunition Manufacturers' Institute, Inc.) tolerance for case length on most rifle cartridges is usually -.020 inch, so for the 308 Winchester, the tolerance would be 2.015 max. / 1.995 min. If your case length gauge trims cases anywhere between these two dimensions, they are acceptable. You can stone the tip down if you want, but 2.008 - 2.009 is within SAAMI tolerance.
