AHHH! I had to look at the pics again to be sure. The one case I saw had R P stamped on the head. Is all your brass that same Remington stuff? In my experiences, the Remington brass is almost always thinner than other brands. So far, it has always worked for me in my sizing dies, but I can feel the difference when sizing, expanding, and crimping. If you sizing die is just a tiny bit on the loose side, that thin Remington brass will not be sized enough.

Roll crimps are supposed to help hold the bullet in place for sure. But they work in conjuction with a good firm grip between the rest of the case and the bullet. A crimp can't hold the bullet in place all by itself.

Try some Winchester or Federal brass and see if that helps.
