The removal of the stock has done wonders for accuracy. still have the occasional stray, need to recrown barrel, but with counterbore and surplus ammo, i can hit coke cans two hundred yards out, not to mention the visceral pleasure of the garbage-can size holes that the mild steel rounds punch through the ice, which I might add, is thick enough to hold people.
made a snowman to test the accuracy on man sized targets, offhand with the ching sling, its a shockingly easy shot at a buck fifty. the trigger work is probably what contributed most to that.
the shimming and lack of pressure on the barrel have helped immensely. Apparently you can put lipstick on a pig because i was outshooting my buddy's noveske AR with open sights.
thanks for the input everyone.
