im new to reloading and have a question.
The speer book i got with my RCBS set said to load .223 casings the max brass case length was 1.760 and trim to 1.750. The question is can you go under that length by a little without making a difference, does it have to be exact 1.750? Like 1.745 or 1.740 make a difference. It would take awhile to caliper check every case for EXACT length. What is the lowest you can go before it to short to use? Im using a AR-15 for target shooting and would like to be as accurate as possible. I got the RCBS automatic trimmer with the moter on it, damn it beats having to crank it! Im am having a little trouble getting it set right. It seems to differ from 1.750 to 1.745. Does it matter?
Thanks
