one note about trimming, sinclair makes an insert that allows you to measure your actual trim length. I suggest doing that you will find you don't need to trim near as much as you think you do.
exactly.
I've made chamber length checking gauges for a few rifles and most are at least .030" longer than max brass spec, one was .045" longer.
No need to trim until you are near that measurement and by that time your brass may have other issues.
I almost never trim brass after the initial squaring up of new brass.
