I have previously made three breech seaters that work fine. Each used .250 round stock for the rod that pushes on the bullet. For a variety of reasons I want to make the next one with 3/16 round stock for the seating rod. This one is for a 38-55 - bigger in diameter than any of the bullets I previosly made seaters for. The bullet will be cast from 1-25. Looking for thoughts, or preferably experience, on whether 3/16 stock is thick enough. What size are the push rods on commercial seaters?
