Ok, started at 4.8gr Win231. Total crap won't cycle action.
5gr, very erratic cycling numerous ftf's <img border="0" alt="[grrrrrrr]" title="" src="graemlins/cussing.gif" />
5.2, better but doesn't get the hold open to work <img border="0" alt="[grrrrrrr]" title="" src="graemlins/cussing.gif" />
5.4 now were cooking sounds good function is perfect!
5.6 a bit hotter and still reliable no high pressure signs on the primers.
I think I'm going to go up to in .2gr increments until I see signs of high pressure.
