Well, heres the deal...RST's chamber and shoot perfectly....BUT even FACTORY 2 3/4 inch loads require a good push to make em chamber...So, I dont consider it a problem, I'll jusr feed it RST's...Perceived recoil discussions always open up a can of worms. I dont notice any more recoil in my 12 bore guns, shooting 2 3/4 loads in shorter chambers....But then again, I shoot a .416 at water jugs....
