If you have an extra barrel.....

An N frame forcing cone can erode just like any other when it's hit with the FlowJet like abrasive force of slow burning, high temp, ball powder. I have several 6" 28's. My primary has such an exquisite action, that yes, I bought an extra barrel off the forum here ($65 delivered ) because I do anticipate killing the one in the gun at some point. The forcing cone is starting to show signs of enthusiastic magnum shooting. I expect to be around for a long time, and I'll be reloading and shooting every weekend until the day I check out if I can help it.
