Many years ago I bought a barrel at an auction for peanuts for a remington 700, and I recently just bought an action for it. The barrel is a factory barrel already chambered so I was going to try and fit it to my action. I got thinking a bit on this and got wondering if I could set the headspace for it with the recoil lug. I was thinking about getting go and no go gauges, threading the barrel to the go gauge. Measuring the distance between the barrel tenon and the action and getting a recoil lug ground to that measurement to set headspace. I realize that I would have to either get a thick lug, or thiner one and it would be easier then setting the barrel back to achieve proper headspace. My question would this work? I plan on someday chambering and threading a barrel for my action once I got the money, and also skill set to do so!
