Default RE: Forming new brass question.

RR
I was/am counting on the magnum primer combined with having the bullet seated into the lands to drive up pressure. That combination should have significantly raised the peak pressure, especially the seating depth. Hopefully the raised pressure will still be with in specs by limiting the powder charge to the starting load. By seating into the lands I was trying to duplicate the effect of a tight chamber by limiting case movement forward as the primer was struck. Curiously my forming loads were also fairly accurate. I was only firing at 25 yards but I still was getting 5 shot groups of 0.25 or less, plenty enough for hunting. I will still have to see what they do at 100 to tell. I left the range when several young men showed up with sks’s and their brass was literally flying from bench to bench.
