New brass length
So I picked up a bag of 100 .223 brass (Federal) from the reloading shop. This was the only brand they currently had in stock for .223 . I measured one of the unsized cases and found that it is already shorter than 1.750 . I believe they were close to 1.740 . Everything I've read or been told so far prepared me for trimming down to 1.750 and I've even been tossing out the rounds that were smaller than that. Can some one fill me in on the what I'm obviously not informed about...
What is the minimum acceptable overall length of a sized case?
I understand that I want uniformity when producing my rounds. So assuming it is acceptable to use cases shorter than 1.750 (which it must be if they sell them brand new like this), I must work to have them all the same length?
Any input or clarification would be much appreciated.
