I'm going to be forming 6SLR brass from 243 brass. To do this, some of the shoulder material will become neck material. Does anyone know if the PRVI brass shoulder material is more like Winchester or Lapua?
Although I plan to seat bullets above the neck/shoulder junction, I would prefer to not form a "dreaded donut" - just in case.
