Before messing with the chokes, I suggest going to the patterning board and determining what you actually are shooting (patterns, that is). If the gun is shooting too tight, then I'd next experiment with some different loads that might get you where you want to be. If all fails, then open the chokes to whatever suits you. Since you took a NIB gun and used it, I assume you want to shoot it, not look at it. You probably dented the guns value more when you began shooting it as opposed to the depreciation that would be caused by opening the chokes. Your NIB gun is now in "excellent condition."
