I already know that you can’t shoot 3.5 in anything less than 3.5 due to dangers of the chamber exploding. However, can you shoot 2.75 and 3 inch in a 3.5 EFFECTIVELY? I realize that you can, but will it cycle better in a 3 inch shotgun rather than a 3.5 inch shotgun? Also, if this is the case, then why aren’t all modern shotguns 3.5 inches? The reason I ask is because I want a shotgun that can shoot all loads and swap out the barrels for hunting and home defense. I don’t plan on always using magnu, but lets say I come across some, I want to be able to use it. Thanks in advance!
