for some reason i.ve had the urge to build a howdah on a shotgun hammergun action was thinking about 444 marlin .i see i see 44mag barrels floating around figure 2 matching barrels would be a good start.got the mill working good and been doing odd jobs with it since its been 30yrs since i owned one. may even do a black powder one. have a doner for that.any thoughts?
