Thanks for all the help guys. Steve after seeing all your posts I though of pming you directly but did not want to appear pushy. Barrel made by Bill Moody. Already made. I am just trying to take the opportunity to educate myself while the gun is being made. Lots of facts and figures out there especially given that "4 bore" allows for a lot of interpretation - I have seen .935 to 1.052. I know bore size is 1.015 and rifling is 1:144. 32" long - 1-3/4 to 1-1/2 octagon tapered.

thx for any words of wisdom here!
