Gettin ready to do an OCW assessment for a load on new Lapua brass. Anyone think I should reduce expected charge versus a workup on fire-formed brass due to possible volume changes.
Is this a considerable factor? Gonna start low and work up, obviously, but should I expect a big difference with fireformed versus new brass and re-do the workup on the fired?
