Tahnka,
My Handloader's Manual of Cartridge Conversions lists the cartridge in question. As stated it is based on the .30-30 Win or .219 Zipper. Minimal body taper and a 38 deg shoulder. A case length of 2.01" ; neck length of: .298" ; and length from base to shoulder of 1.63"
Only one load is listed: 50 gr. bullet with 30 gr. of IMR-4895 for a velocity of: 3575 f.p.s.
Pretty potent lil' number, eh? But sadly it can be beaten by the .22/250 quite easily with factory loads... You can read more about it in P.O. Ackley's book, Vol. 1...
