yea...the slug barrels are oversized to allow the rifling action the name rifled slugs is misleading since its use after they stopped making round pellets..remember how they stood side by side in the civil war? thats cuz if you shot with an "unrifled" bullet you would have no chance of hitting nething diretly in front of you, it would spin all around the place like crazy. the rifled bullets allow the normal barrels to shoot MORE accuratly than with unrifled slugs but you are still gonna be wobbly as all get out ..ps, dont try it on double barreled guns :yes:
