Re: 50 Peacemaker?
I seriously considered this cartridge for a Ruger #1 project, however, I am trying to keep the rifle at the 15 pound mark and no brake. I've decided to stay with the .378 Weatherby for that project with a 34" tube for long range coyote plinkin'.
Actually, J.D. calls the cartridge the "Peacekeeper", (you sound like a Colt afficionado!), and the velocity realised with the 750 grain pills runs right around 2200 fps. Still pretty damned impressive!
