does the Traditions Crockett rifle have some kind of a pattened breach. buddy of mine has one,while wiping between shots he gets the ramrod and jag stuck in the barrel and ends up snapping the ramrod off flush with the muzzle. after messing with it for several days i ended up getting enough 4F into it through the nipple hole to shoot it out. took it home to clean it,took the barrel off,put it in a bucket of soapy water,wire brush first,then a bore mop,then a cleaning jag with a dry patch,damned if it did'nt get stuck also.fortunately i was useing a long metal range rod for cleaning and managed to get it out. at the very bottom of the breach there seems to be a lip that is catching the jag.has anyone else ever had this problem,is there anything that can be done to fix this. also does anyone know the thread size for the nipple,i believe they are 1/4X28 but cant recall for sure...thanks!
