Medieval Handgonne Build

Hey there, smokers. Havent posted here much, thought I'd come gloat about a project of mine... I had a medieval handgonne barrel machined from steel, and got it in the mail today. Just the barrel weighs six pounds. It's .70 caliber with a .50 cal powder chamber, correct to the original I copied. I plan to mill historically accurate serpentine powder to use in it, too. It has a socket at the base to go on the end of a pole.
