Well hello all!! For some reason, I've become interested in the subject of medieval handgonnes, and would like to possibly have one made for me in the near future for shooting at the range. There are a few custom makers out there making quality pieces at good prices. For those not familiar with them, these were used from about the 1200's through the 1400's and are perhaps the earliest true firearm ever. They were eventually replaced by matchlock guns. Handgonnes are generally nothing more than a short, stout metal pipe with a touch hole, mounted on a long wooden shaft: I am thinking about having one made in .62 caliber so I can use the components for a muzzleloading 20 gauge shotgun. I have watched many videos of people shooting these, and it looks like great fun. They are very simple and crude, but seem awesome. Does anyone out there have a handgonne? What caliber is it? I am having a hard time finding what the average caliber would have been during the medieval days. Any input on these ancient guns is appreciated. Thanks all!
