Accuracy tips for 300 Blackout brass...Lee collet die and shoulder set back...
In this video I introduce the idea of using the Lee collet die for the 3OO Blackout in an unconventional way. I propose using the collet die after full length sizing as an additional step. I have found doing this particularly on home made, un-fired, brass improves accuracy by about 50% in my case. I also talk about adjusting shoulder set back once brass is fire formed to improve accuracy as well. Hope you like it.
