300 WM OAL Question
Why does the OAL of my loads vary ? Loaded 9 rounds and random check of lengths were : 3.753, 3.749, 3.746, 3.744. Componants were:
R-P cases, 150 gr AccuBond, RCBS dies, Stoney Point OAL gauge(the one with the adapter that mounts on the calipers and you slid the loaded round into the adapter - bullet first), Mitutoyo dial caliper. This situation has come up on other calibers as well.
