Shotgun shells
Shotguns don't use bullets. Do you mean without a case or non lethal projectiles? If so, yes they have caseless ammunition.
On modern shotguns, the information about the correct ammunition is typically found on the barrel or receiver, often stamped or engraved. This includes details such as the gauge, chamber length, and any specific ammunition restrictions or recommendations. Additionally, the owner's manual for the shotgun will provide guidance on suitable ammunition types. Always consult these sources to ensure safe and proper use.
Remington makes a variety of rifles and shotguns using various sizes of ammunition.
