Mr. Stanton: Really interested in a .50 cal but after shooting my guide gun in 450 Marlin from prone for 20 rounds 1 day I think I need more weight and a different stock design. I love the look of the 50 Alaskan and note that WIN used the basic 348 case dimensions to design their new short magnum. I have a 416/350 short action Ruger that I would not mind rebarelling as it has never shot well. If the 300WSM was necked up with minimum taper could it be given enough shoulder to headspace well. Might this fat case feed well through an unaltered Ruger short magazine rifle? What sort of ballistics could I expect out of a fat 20" barrell?Is this a practical conversion?
