Ok that's a good thing, left the chrono at home last Sunday which cost me some very important data, did try 67.2 grns of IMR4350 at .030 off while the group was a tad under 1/2" bolt lift was TIGHT(pressure). Also shoot 65 grains at .050 off with no pressure, but groups were terrible I will try .030 off at 65 and work up like I intended to WITH chrono! Thanks!!!
