I am having a trim to length quandry. I have two books, Hornady 8th edition and Lyman 39th edition. The problem I am having is my cases are short. The caliber is .380. The cases are new and once fired. The two books call for .675-.677 CTL. The new cases are Winchester and measure between .670-.674! The once fired are .672-.675 after resizing. How am I to set bullet depth? Do i cut them all to a reasonable static shorter length and not worry about what the books say?
