I recently picked up Tristar Cobra III Field pump in 12ga with a 3” chamber. I took a look on the Tristar website to get more info about the gun and was surprised to see it say the gun “allows you to shoot light target loads to heavy waterfowl loads.” I find this pretty confusing as I don’t see any reason why I couldn’t put some 00 Buck or a few slugs through it. I looked at the Cobra III Force and it says the same thing except replaces heavy waterfowl loads with heavy buckshot loads. Is there some reason I wouldn’t be able to put buckshot through it? It came with a choke box with your typical improved, modified, and full.
