Nice setup. How's that case trimmer work? Nice and precise? Post pics of your groups when you can.
case trimmer works as any standard case trimmer i guess. lock it in place at the shortest you want the case, then screw in the allen heads. it does have a "rough" bushing and a "fine" bushing to get it to an exact science with calculations, but what i do is shave a case down to be my reference. the push the bushings to the max and touching the case mouth, i lock it down so from there it's not going to go past it.
it's like 90$ or so. im sure u can find another brand that does the exact same thing cheaper, like lymann or lee. i just went with the green one to contrast my red, it's like christmas all year around.
