I can't say much for either caliber, but I can say Wayne does dang good work and I would recommend him to anyone!! I've had a .25-06 Ultra rebored to .338-06 and a .38-55 Target rechambered and rebored to .405 Winchester, they both shoot sub moa, can't ask for more than that, his work is exemplary. The only problem I see right now is Wayne is in the middle of moving to eastern Oregon and probably won't be getting any new work done soon...plus there's hunting season coming up and I know he's a hunter!!!
