I am starting to brainstorm a project for a while from now, but with the long lead times on barrels, I wanted to start looking at options. What is a good source for the above profile barrels. I believe Colerain makes the TRS rifle barrels, so they would have something in the 46 inch and .75-.77? What about a barrel around 38inch and .69ish? Is it a feasible proposition to cut down musket barrels to size?
