Brent, set a target paper at about 16 yds. . Start at a low ready position raise the gun to your face and fire when the mount is complete as in hunting. fire 8-10 shots at a single aiming point with the right barrel. Change targets and do the same with the left. With a consistent mount you will be able to see the center of the several patterns. This will show you where it shoots for you. Then repeat with one of the other guns you shoot well. Then do it with the SKB you don't shoot well. What matters, is where the patterns hit not how much the barrel is bent. Bending barrels can be a viable method of fitting a gun, if the adjustments to the stock are too extreme to be viable. Shotgun tubes bend fairly easily, intentionally or not. Also regulation of the barrels are not guaranteed. If it shoots where you look don't try to make adjustments to gun AQ based on information from gun B
