Can a Harrington and Richardson 20 gauge Topper Classic shoot steel shot for waterfowl?

The Harrington & Richardson Topper Classic 20 gauge shotgun is chambered for 2¾-inch shells and can safely fire steel shot. However, it is important to note that the barrel of the shotgun may not be steel-shot compatible.

To determine if your Harrington & Richardson Topper Classic is steel-shot compatible, look for a marking on the barrel that says "Steel Shot Proof" or "Steel Shot Approved." If you do not see this marking, it is best to avoid using steel shot in your shotgun, as it could damage the barrel.

If you are unsure whether your shotgun is steel-shot compatible, it is always best to consult the owner's manual or contact the manufacturer for more information.
