Oh No! My Shells Won't Fit

Here is a quick method of finding out if the mouth of the reloaded case is flared from too much pressure in the final crimp stage. Using a vernier caliper with a dial indicator (if you don't own one, you should) check the dimension of the base (.745) where it meets the plastic hull. Then check the dimension of the mouth of the case. The mouth, when crimped right, should be about ten thousandths smaller than the base where you measured it. Your cases will drop in and eject without trouble if those dimensions are correct. JF
