Hi I have a syracuse hammer gun with Damascus barrels, actually two of them. While measuring the bore diameter with calipers I'm coming up with .740 - .744 on two sets of barrels. I know it's not the most accurate way to measure them but I'm confident I'm within .002. So I'm wondering at what diameter were these originally manufactured to ? I doubt either of these sets were honed out, they both look horrible. I plan to clean up the bores they both have plenty of wall thickness. Being that they are both way past the .729 bench mark I was just trying to find out if they used a different standard for Damascus years ago. Thank You for any advice, Tom
