Well fellows, the only caliper I have on hand right now is a digital caliper and I don't know how accurate. I will take the gun to my dads this weekend and get a proper measurement. The readings I get though are 0.69 which I guess confirms that it was a 14 gauge at one point. And from what I get with my caliper the chokes were opened to cylinder because I get the same reading. Which I guess puts it at xtra full choke for a 12 gauge. However, I am going to make 1/4 length 20 gauge reducers for this gun.
However, I will try and get a more accurate reading.
