Generally speaking if you have a US made shotgun with "forged steel" barrel(s) that was made after 1925, and is in sound mechanical condition; it will safely handle any factory multi-projectile ammo that is of the correct shell length for the chamber. Even older guns, that are of questionable soundness, rarely fail. Thus, many persons insist that they are safe to shoot based on past experiences. With ballistics matters, there are more probabilities than certainties.
Do not shoot 3" shells in a 2 3/4" chamber, as doing so will create abnormally high pressures, even though the shell will seem to fit OK. Shooting a lot of 2 3/4" Magnum lead "BB" to "OOO" buckshot through a full choke barrel is not to be recommended, as it my loosen the choke; but it is not likely to cause obvious gun damage from a few shots. Steel shot is harder on barrels and chokes than lead shot. It should be used only in guns built to tolerate it.
Simply stated, heavy loads stress and wear any gun, more and faster, than light loads. Heavy loads have their legitimate purposes; but just punching holes in paper targets or shattering clay pigeons are not usually such purposes.

It handles 2 3/4" and 3" shotshells. I believe it is a full choke I shot a round yesterday of 00 and I have a bruise on my shoulder. Any more info would be appreciated but I think you just about said everything necessary.
Also the 00 is 3" Remington Express Magnum 00 Buckshot. It has a lead warning so Im assuming its lead shotshells. It sure kicks alot so Im going to kind of stay away from it and just for occasional purposes.
