Lost Sheep suggests not automatically screwing the die another half turn past first contact in the
crimping operation, but rather do it 1/6 turn at a time until sufficient crimp is achieved. That is good
advice.
That 1/2 turn first suggested is my own experience w/ the 500 -- both to prevent bullet 'back-out'
upon the significant recoil of the 500, and to get good/consistent ignition with ball powders as/when
loaded. (And I'm using heavy lead bullets as well, where significant crimp is useful)
YMMV, of course.
