I wouldn't presume to think i could "hand lap" a new match barrel better than the guys who "lapped" it at the factory.... barrels on many "factory" guns are possibly a different matter,, I've scoped some that looked like railroad tracks.. I know 2 or 3 guys who decided to lap their match 22 rimfire barrels & they shot worse,, when scoped, they had lapped the lands clean off several inches of the bore!!! Polishing with steel wool can do nothing but take off the loose, rough edges,, it won't take off any steel otherwise.
