Newbie caster needs help. I picked up a Lee Bator mold for my 223. I also picked up a set of RCBS 223 dies. I was trying to setup the seater/crimp die last night. The end of the bullet is being deformed by the seater. The seater is leaving a ring imprint in the end of the bullet. Depth and crimp seem to be fine. Has anybody had this problem and what is the remedy?
The bullets are for use in a single shot handi rifle. The brass is once fired PMC. Using a homemade expander for flaring the cases (basically a tapered pin) No lead shaved during the seating and crimping. Lead is being melted in a Lee electric pot, temp unknown. Lead is scrounged scrap but believed to be pure lead. Looking to duplicate 22LR performance with loading so not trying to get above 1700FPS.
