That T/C NW edition is a 1-48 twist. You could have done better with a different NW edition rifle using a 1-28 twist if you want to shoot conicals. A 1-48 will limit your selection a great deal and the damn thing still has the messed up T/C QLA. When you get tired of fighting with it go grab a Optima V2 NW edition. You can also convert it back to 209s for hunting normal seasons too.
