still breaking in bbl and getting new brass fired to fit chamber,,doing a little tuning while breaking in just to get an idea what it will like. then I fine tune it starting at 100 rounds ..shot these with brass straight out of the box CCI 450 primers and H4350 with the 135 BIBs .016 off the lands,,the blue dots are 2 inches..
42.0
42.3
42.6 grs and I think with the long freebore I will try 42.9 and 43.2 as the groups were tightening up and I wasnt getting any pressure signs,,but I would be happy with the 42.6 group if it starts opening up any higher,,
the first 2 arent much but I like how it gets tighter the faster it gets,,
