m1 garand man Start off with a new can of powder you might have too many fines,try resting the barrel real close to the muzzle,pull all of your barrel pins and wrap the pin locations with masking tape,weigh your round balls and mike them also,read your patches, apply the lube different,switch lubes,pull the barrel and see how the stock reacts with no barrel in it ,if it twists a little that could be it ,wipe the bore after every third shot for a more co nsistent bore.One of these might be it.Curt
