Hi everyone, i just purchased a marlin 336 in .35 and it has a swift 4x-40mm scope on it, i bought a box of 20 winchester powerpoint 200 grains, i wasn't real impressed with the accuracy it was grouping about 2 to 3 inches and would be all over the place randomly, i took it into the house and the screws on the side of the action were loose, could these be causing the problems? the bore looks very good to so i don't think the barrel is shot out...it would group but i would adjust it and it would be double what i adjusted it...any suggestions?
