[QUOTE="Kansaswoodguy, post: 1526213, member: 83267"] I would not trim to shortest case length either just book length. Clean cases are pretty to look at but do nothing for accuracy. If I don’t trim my cases and there is differences in case lengths my groups open up to around 1.25-1.5MOA after trimming my groups drop to around 3/4MOA. I use the cheap Lee case trimmer that can be chucked up into a drill and spins the case this is makes it very quick to trim and chamfer the cases and they can be cleaned with 0000 steal wool held against the cases when spun. I tumble my 223 brass but I shoot hundereds of rounds of it. I never tumble my 6.5 Creedmoor brass just resize/deprime it pushing shoulder back .003 run it in the Lee trimmer, chamfer then use the steel wool on the cases to clean them up a bit and use the wool on the case mouths to give them a quick polishing.
