That is cool as hell! I've never shot one, but the cartridge has always intrigued me. If a guy could rebarrel a 336 to it, and it would shoot as well as yours it'd be worth doing. I love my Marlin lever guns, and I love centerfire .22s. Combined would be uber.
I'm thinking there isn't any reason a 336 couldn't just be rebarreled to shoot a Zipper with no other mods. Anybody try it?
One note, when I went to find dies for this I found quite a few more sets of Zipper Improved dies for sale than straight Zippers. Seems there might have been quite a crop of improved Zippers floating around at one time.
