I shoot .223 and always case trim initially as the once fired can be at or over the 1.760 limit. The lee trimmer knocks it down to 1.753 approx. and I don't notice much, if any, stretch (although I'm not loading to max pressures) after shooting my reloads. The variation in length varies a lot between case manufactures and even in similiar batchs. I use a dial caliper ($14@harbor freight) and do them (the free range pickup) while watching movies. Pistol cases don't need trimming BTW.
