I'm using the same Lyman .44 mag die set I have been using for years. For some reason I can't get an even crimp on the Speer shot capsules. I can get a perfect crimp every time on seating any other bullet of any make, size and shape. But when I go to seat and crimp the shot capsules I get an uneven crimp. One side, about have of the edge of the case is crimped just right, the other side or half, doesn't have a proper crimp. Can't figure it out. Anyone else experience this using the Speer capsules?
