I've said it before and I'll say it again: About 40 years ago, when the truth was more important than pimping for the advertisers, the Q & A section of the American Rifleman contained the following question: "does lengthening the forcing cones and/or back-boring reduce recoil?" This was back when all this barrel magic crap was just coming on the scene. The answer given was: "nothing you can do to the inside of a shotgun barrel will reduce recoil unless it also reduces velocity". This was true then and it's true now. The only difference is that magazines now, including the Rifleman, are little more than parrots, accepting anything in the manufacturers' release letters as gospel, no matter how outrageous the claims. The reason gun makers now offer much longer cones and over-bored barrels is that so many in the buyers' market believe this nonsense. The facts haven't changed but when lies are repeated often enough, people start to believe them.
