I've got a Contender barrel in .256 and have formed quite a few cases myself, even though I lucked up on a fairly good supply of factory ammo several years back. That stuff is getting so scarce I only shoot a few rounds on rare occasions. I had a chance to get a 62 in .256 about 8 years ago and let it slide for some forgotten reason {lack of funds likely}. I also ran across one of the old Universal Ferrets {semi auto based on M1 Carbine} in .256 a couple years ago but it was too pricey.
