Rio Ammunition RoyalSteel Super Magnum 12 gauge shotshells pack serious knockdown power in a 3.5-inch magnum load. Built with 1 3/8 ounces of steel shot and a 2 shot size, these rounds are engineered for waterfowl hunters who need reliable, hard-hitting performance in demanding conditions.

Rio's steel loads maintain consistent patterns downrange, helping you connect on passing birds and distant targets with confidence.

The 3.5-inch magnum format delivers the velocity and payload needed for extended range shooting without forcing you to compromise on accuracy or pattern density. Whether you're hunting from a blind early in the season or working a late-day flight, these rounds give you the ballistics to succeed. The 25-round box format keeps ammunition organized and portable—enough for a solid morning or afternoon hunt, or a productive range session dialing in your shotgun.

Frequently Asked Questions

What shotguns can safely use Rio RoyalSteel Super Magnum 3.5-inch loads?

These 3.5-inch shells are designed for 12 gauge shotguns chambered for 3.5-inch magnum ammunition. Always verify your shotgun's chamber stamp before loading. Most modern 12 gauge pumps and semi-automatics accept 3.5-inch shells, but some older or specialized firearms do not. When in doubt, consult your shotgun's manual or contact the manufacturer.

Can I use steel shot ammunition for all hunting situations, or are there restrictions?

Steel shot is required for waterfowl hunting in most U.S. jurisdictions and is prohibited for lead-free zones in some areas. However, steel shot may not be appropriate for upland game or other hunting types in your region—check your local game laws before your hunt. Steel shot also shoots and patterns differently than lead, so practice with your specific load to confirm your point of aim and pattern at realistic hunting distances.

What does the 2 shot size mean, and what is it best for?

Shot size refers to the diameter of individual pellets in the shell. Number 2 is relatively large for steel shot, providing good energy and penetration at range. It's a popular choice for waterfowl hunting where you need hard-hitting pellets to ethically take ducks and geese at moderate to longer distances. Smaller shot sizes hold tighter patterns but deliver less energy per pellet; larger sizes open patterns faster but hit harder. Pattern your load at the distances you hunt to confirm it meets your expectations.

How many shells do I need for a typical hunting day?

A single 25-round box offers enough ammunition for a morning or afternoon hunt, practice session, or range outing. Many hunters carry multiple boxes to account for extended hunts, practice before heading afield, or simply to have backup ammunition. Consider how long you'll be in the field and your typical shooting volume when deciding how many boxes to pick up.
