Anyone lined a barrel for the 45ACP round? I don't know if a factory NEF .452" barrel exists. Guess the new 45LC at .454"[?] would be close enough.
I looked at the bore of my .357 Mag Handi Rifle [NR series] and am very impressed with the quality of the bore. I looked only at the first 1/4" of the muzzle with my microscope [binocular] and it is a FINE job of reaming and rifleing. Fine enough that I'll take it to a buddy's house that has a HawkEye Borescope to check out the rest of the bore. Shoots great,,,what a great cartridge for the Handi rifle.
I have a 45 cal muzzleloader octagon barrel blank that I have thought about fitting to my Ruger 77 .308 bolt face action, and chambering to .45ACP. Should be the "CB Cap" of 45 bores. I don't know if its a .450/.452/.458 bore, tho. Ever since I read about an Argentine Mauser being barrelled to 45 ACP years ago in RIFLE magazine, I've wanted to have one. Guess it'll be a single shot, but that's ok with me.
