I have 280 pieces of new 7mm wsm brass I'm beginning to process and the book trim lenght is 2.096 but only about 10 pieces of the first bag would be trimmable to that lenght with most pieces falling between 2.092 to 2.094. Normally I would just trim to the shortest lenght and that is what I will probably do since this brass is virtually unavailable but what are the negatives of trimming everything to 2.09 and calling it good ?
