TexasRick,
Count me in as one who is definitely interested in this fine ol' cartridge. With modern day powders/bullets available the posibilities to breathe new life into the ol' 57mm case in various bullet diameters. This reasoning led a good friend in Alaska and myself to design the 338x57 MAI(Mauser Ackley Improved) using the 200gr CT/BST and VV 150 powder to produce velocity of 2800fps + with pressures less than 59,000psi.
Hope you get the rifle. It should be a winner in all respects.
Regards,
Ol' John
