Oh yeah - the H. Whall - 11 bore - ball and shot gun. Breech a full 1 1/4" across the flats - 36" long. The barrel is pretty rough and hard to clean, but I used it for the smoothbore Trail Walk event back in 2006 - and won second place. I think I missed 3 targets out of 21 total. I shot the course in the afternoon with a rifle and missed the same 3 targets for second place - HA!, except with the .40 cal rifle, I shot through links of 2 chain targets, whereas with the big smoothbore, I missed them clean.

Here's a nice cap gun of my bro's. 15 bore. I shoot it better than he does - ticks him off - I've not missed a clay bird with it. The bores are quite good. .675"
