I recently bought an old .410 barrel with a brazed on locking lug. I am wanting to reweld this lug on a .30 caliber barrel blank and chamber it in 7.62x25 Tok or 30 Mauser. I am having a problem getting the barrel to even fit on my frame. The pin that activates the ejector seems to be in the wrong location and closing the barrel on the action is very difficult as is opening it. Once the pin passes the shoulder in the reciever the barrel locks up fine, but getting it fully open or closed is a real pain.
Any Suggestions?
