Hi Dave, good to see you over here! Your experience and expertise are most welcome and will be greatly appreciated. BTW I agree with Froggie about your Ballard and with Mark about your Gibbs barrel. Rocky Gibbs, albeit not a very aesthetically-inclined individual, was nevertheless a world-famous ballistics experimenter and wildcatter, a pioneer of high velocity much like Roy Weatherby except without the Weatherby showmanship. His claims, like Weatherby's, are open to debate but are widely known and form the basis for some of our modern cartridge designs. One very serious caveat when reloading for this cartridge: Gibbs' wildcat designs move the original shoulders forward to such an extent that very special precautions are required to prevent head separations at the webs, but I figure that you already know this.
Welcome again, regards, Joe
