I am reloading 45ACP, 200gr RNFP cast bullets. All equipment has been cleaned and adjusted. The OAL of most of the rounds are 1.244. For some unknown reason I will get a few rounds that have an OAL of 1.18. I tried each round in the shell plate to see if the problem followed one particular slot, but the OAL was not consistent with any particular slot. I cannot figure out why I am getting a few rounds seating the bullet so much deeper. The min OAL according to my book is 1.19. Any thoughts or suggestions?
