[QUOTE="BountyHunter, post: 59360, member: 12"] NO way would I lap a factory barrel or let anyone tell me he can do it without damaging the muzzle end of the barrel. Dan Lilja makes a cut across the blank about 3/4" down from the muzzle ends of the blanks he sends out. Lapping will wear out the ends of the barrel blank and enlarge the bores. On one end you chamber it and on the other you cut off 3/4-1". Now if Dan Lilja and every other barrel mftr cannot hand lap without enlarging the bore end with the number they lap daily, do you really think a local gunsmith who laps a barrel once a month can do it without damaging the muzzle end???? Fire lapping if carefully done will help but got to watch throat erosion. BH [/QUOTE]
