Interesting stuff. I am NOT a machinist & have no such skills. How ever I have been wondering about setting up barrel re-boring / rifling. What is required to do this? I have corresponded with a few barrel be-bore guys before. Considering the thousands of old barrels available here & the fact that a new chrome molly Douglas re-barrel job cost about US$600 and Kreiger would be US$750, I thought it might be worth doing some reboring as a part time business using the right machines.

Just a pipe dream probably.....!
