i have 2 stevens model 200,s 1-30-06,1-.223.both have 3x9 nikon prostaff scopes on 1 piece leupold mounts.a retired gunsmith who speacialized in triggers did both for $30 a piece to 2.5lbs.i didnt clean after every round,i have removed copper inside barrels twice.im only getting 2" groups off the bench w/both rifles.i dont handload anymore.my question is what would be some simple things to do to improve accuracy.i have thought about a recessed target crown,$75,but dont want to waste the money if would not help.what are your thoughts out there?thanks,Bill :)
