[QUOTE="bigedp51, post: 1729790, member: 28965"] From reading the OP posting it sounds like the Prvi Partizan brass is once fired from another rifle chamber. Meaning these cases were fire formed in another chamber and do not fit in the new chamber. When you full length resize a cases you are squeezing the case smaller in diameter. This squeezing makes the case grow in length until the dies shoulder pushes the shoulder back. So again if the Prvi brass was fired in another "larger and longer" chamber even after sizing the case wants to spring back to its fired size. So again pause at the top of the ram stroke to reduce brass spring back or size the cases with a small base die. Also make sure you have the die adjusted making hard contact with the shell holder with press cam over.

The Prvi cases have a larger base diameter and are .010 thicker in the base and have thicker rims. Meaning the Priv cases are made Ford Truck Tough and are not junk.
