I have great Plains pistol in .54 cal. I saw a .50 cal. Barrel for it at midsouth for $39. I ordered it so that I would have a second shot no matter which of my rifles I am using. UPS brought it this morning so I cleaned it up and took it out to shoot. With 40 grains of Goex three F powder and a PRB I was getting six inch groups at 20 yards. I had some 320 grain R.E.A.L. bullets For one of my rifles,so I tried them with the same 40 grains of powder. I get a inch and half group at 20 yards. If I knew how to do pictures I would post that target! I am happy as a dead pig in the sun shine with that barrel!
