I have a TC white mtn carbine w/a 21" gmb 1/28 twist. Today I had it apart for cleaning. It occured to me that if the 21" bbl would fit the wmc, would my .45 hawken fit in the wmc stock? Wel it did! and it actually fit and balanced great. now I wonder that if it will shoot w/that setup. It is just muzzle heavy (steadier). I knew gmb bbls fit, so know what should I do? Shoot it, order another bbl?? Help!!
