So let's just say I finally got my hands on a mid-50's build, anyone have dies? lol
Also have a second one that I haven't found a barrel stamp on yet (will do a chamber cast), but the bore seems to be a 6mm/243.
Neither of these are mine, but a friend who inherited them and knows little to nothing about them....

Quality brass has .244 Remington brass (need to fire form)....hopefully in the next month will have the first rounds down range on this old bird in decades

My wife is starting to think I'm nuts, I'm getting a few "special" guns
