Yea I understand, a friend just picked up a Ballard re-barreled to 44-77. He is making brass from .375 flanged, The rim is thinner but once they are fire formed he should be ok. I am not sure what would be the harder pull on your arm, the caliber or the rifle itself. If need by, and you get the rifle, I can form the brass for you. Its a pretty long stroke but the full length die I have from Reading can do it in one shot but I prefer to pump it a bit. Talk about a case with a damn long neck, 45-70 necked down before its trimed, heck of a looking thing.
