Hi All, I have been shooting muzzleloaders for over 30 years, mostly TC hawkens and Traditions Great Plains rifle. About 45 years ago my dad bought a CVA 54 caliber Hawken. He bought it as a kit mostly for the fun of the build. He brought it out to my place to shoot it about 25 years ago and I remember that my .530 round balls and .015 patches basically fell down the bore. Fast forward to this spring and my dad passed away and all his guns came to me. I have been getting all his old winchesters etc out of moth balls and out shooting. I took the CVA out this past weekend. The manual for the CVA 54 Hawken says to use a .530 ball and .015 patch. When we shot it I used a .530 ball and 2, .015 patches and it still was just an easy push down the barrel. When I cleaned it at home I measured the bore with a caliper and it measured .565. My TC 54 Hawken measured .540. What gives here?Do I just use a .530 ball and real thick patch material? I also took one of my 54 cal Lee REAL bullets and it just fell down the barrel? Any advice is appreciated. My dad did such a nice job on the build I want to get this thing shooting and get a deer with it this fall! P.S, the barrel is clearly marked 54 caliber.
