It should be noted that the LEE FCD is a collet-style die in 44-40. As such, it is not "resizing" the lead bullet. Without knowing more (actual diameter, cannelure, etc.) about the bullets being used it is really hard to attempt to even diagnose the problem, much less suggest a solution.

With the collet-style LEE FCD there is at least that 2nd option for crimping. At 44-40 pressures it probably had much to do with the tubular magazine and not enough crimp, what ever the version.

Cheers!

P.S. The LEE collet-style crimp in a cannelure won't go anywhere, IMHO.
