I'm having and issue seating 45 acp cast bullets slightly crooked, shaving lead causing my fussy 45 to not always go into full battery. I'm using M die for flaring (which helped a bit), lee dies to size, seat and light crimp separate. What I'm wondering if a sliding collate die like hornady will fix the crooked bullet/ shaving lead issue? If it helps, I'm loading Lee 452-200-RF boolits.
