You do not mention the kind of press you are loading on. Single stage or progressive? Sometimes on a progressive press, the various other operations prevent the ram from going all the way up and this will cause OAL variations. The big culprit is the sizing operation. This can be a particular issue with mixed brass that takes differing forces to size completely.
