I don't have body die? I have kilos of RE17.
I might drop back to 44gn and see how I go...? Or when firing a fireformed case with 260AI for first time check case head with mic...? I measured a new Lapua case and it is 11.91mm - the NS case are all 11.91mm and 11.92 with 1 case at 11.94mm. My Mitutoyo only goes 2 DP in metric and 3 DP in imperial...do I need something much flasher to measure 0.0005 (mm?)??
