forgive me if I should know the answer to this, but i am still green. I have recently started reloading for my .270 win and .223 with fabulous results accuracy wise. I have a question about trimming when the cases get a little over max length. In the reloading books, it says the max case length for .270 win is 2.540 with a trim to length of 2.530. I have about 30 rounds of brass that I have shot twice, and about half of it is right at the 2.540 mark with the other half being between 2.541 and 2.548. The brass that's a little over length will feed fine through my rifle, but I wanted to know if Its ok to load it on up at a little over length, or do I need to wait on getting a trimmer before I do?

thanks in advance!
