I have been handloading for a year or so and have a few questions about case prep. This is what I have been doing. I usually buy 100 brass when I get a new rifle. I make sure they are from the same lot number. I run them though the sizer die. I measure all the brass and cut all the brass to the lenght of that shortest piece. I debur the brass then put them though the vibrator. After that they are all clean and ready to be loaded. My question is do I need to measure and cut the brass to the same lenghts if they are not over the max length? Is this a step that is wasting my time? Also I noticed that when the round is put together that not all of them are the exact lenght. Some times they will be .006 different. Is this normal? Those are with RCBS dies. I have been able to get them to the exact lenght with some hornady dies that I use by making them a little longer and shorting them a little at time till I get them all with in .001 or each other. Any insite would be great.
