Are people running the mandrel from SAC in their dies? If so what is the best way to determine size?
I currently only run custom Whidden bushing dies and no mandrel (I own mandrels for new brass) without any issues but since the SAC is one step I'm more open to the idea of running a mandrel but want to know what others are doing with their SAC dies in terms of mandrel vs no mandrel.
This is about SAC mandrels only. I'm running it in 7 PRC
