RE: "Accurizing" a new gun to shoot tighter??
Whatever you do-DO NOT use that firelapping kit!!! I have seen several barrels ruint because of those kits. If you want a smooth bore,handlap it. The firelapping won't let you feel rough or tight spots like handlapping will. PLEASE DON'T firelap your bore-handlap it,more trouble and takes time but you'll get great results as opposed to possibly ruining your bore.
