Just got back from shooting a round of skeet and trap. Tonite my skeet gun was a Dickson and Son, Churchill style, BL. This fall I had it out to Mike Orlen to open the left barrel from full to LM. Right is original Cyl. Tonight I shot the 2nd box of ammo out of it. After the skeet round, I heard a buzz as the barrel tapped on my leg. Rib is loose from the muzzle back 10", lifted up about 1/16". Is opening the choke generating enough heat to melt the solder? or is rib seperation just part of the vintage game? S--t happens, so to speak. Not at all blaming Mike as he would have had to notice the seperation and made mention of it..... Question, Now who is the go to guy to have it fixed? Cost? Randy
