BlaserGuy, the 375 VC caliber is awesome...something on the order of a 375 RUM or 378 Wby, but in a double rifle. If you wanted to up the ante, load it with 350gr bullets for more insurance on Buff.

PS: If you change you mind and have an R93, a guy I know is selling a Safari barrel in 416 Rem with sights and magazine for $900 :-)
