So I just spent a couple hours chasing the overall length of my 30-30 110 grain loads. I started long, about 2.5 inches and walked down to the 2.475" length I want. Once there, it would not stay consistent and varied from 2.465 to 2.479. This is the first rifle cartridge I've reloaded, but didn't have this issue with the 9mm i tried before. Is there something wrong with the die? Is there some technique I need to develop? I ended up backing the die out after each round and walking it in with quarter turn increments. Even with all that, it would sometimes overshoot from 2.485 to 2.468. I took the seating die apart and didn't see any trash in there.
