Rio has been available to the US market since 2002 providing American Sportsmen and Women with high quality affordable shotgun cartridges in various gauges and for various activities.

Rio's parent company MAXAM is a global leader in the explosives industry and supplies munitions to civil, military, and sporting markets in more than sixty countries. In June 2015 Rio opened a start-of-the-art 105,000 square foot North American facility in Marshall, Texas assembling a wide range of hunting and target loads for the North American market.

Rio Royal BlueSteel is loaded with perfectly spherical steel shot for use where regulations call for lead-free shotshells. It's ballistically engineered to retain energy down range and generates less pressure, a more consistent pattern and better efficiency than competing brands.

The Ducks Will Fear Your Blazing Muzzle!!!!


These shells hit like a ton of bricks! Not quite as good as the Rio Bismuth that I soon hope Rogers offers but until then, these will be a staple in my blind bag for years to come.
