crimp oh my!
Highly recommend revolver-rd crimping using the superior Redding Profile Crimp die.
Tested, confirmed -- more consistent velocity and accuracy.
(Crimp = I adjust for HEAVY crimp by turning down the die in until I crush or buckle the case, then I begin ever-so-slightly backing off until I reach a 100% no-crush-or-buckle sucess rate.)
