Dillon RL550B, 223/5.56, Video 48, Cartridge Case Trim Length and Blowing Up A Rifle

I hope this video helps those who are uncertain of trim length and how it needs to be addressed. You need to make certain that your cases are not too long because that is the safety concern. If you trim back a few thousandths too much that is not an issue provided you keep them all the same for uniformity. When using a case gauge always make sure to read your instructions. God bless and thanks for watching. Highboy
