The Dillon swager will not swage the IVI pockets, deep enough.
Maybe.I've never had a problem swaging IVI brass with my Dillon. Maybe you didn't have the swag rod adjusted correctly.
Maybe.
I followed all instructions, then You tubed, asked on here and tryed every adjustment possible.
The primer would stick out of the pocket about 1 mil.
I only tryed CCI primers though.
Simple test, measure the height of the primer and primer pocket depth with a vernier caliper. I had to uniform 300 Lake City 7.62 cases because my primers were taller than the primer pocket.
