Hi all. So I have just a quick question that hopefully someone could kindly help with. I am in process of looking for a scope mount for my TC New Englander in 54 caliber. Someone may have one available from his old New Englander in 50 caliber, but I was just concerned that the outer diameter of the barrel might be different. So, would anybody here have a .50 caliber barrel they would be willing to measure for me for comparison? Thank you in advance for your time.
