I just got my first Lee die set ... in this case for the 30 Carbine. All my other die sets have been Lyman, RCBS, and Dillon. The case mouth flaring die has a peculiar property: on the downstroke of the lever, that die really insists on holding onto the case wall. It takes a bit of force to separate case and die and it does so suddenly. Mind you, it does the job very well. No problem there. But the final jerk on separation is “unusual”. Is this typical of Lee’s expanding dies?
