Rio Ammunition

The RIO brand was founded in 1896 and since then it has gone from strength to strength and is now sold in more than 60 countries serving millions of hunters and shooters around the world. RIO’s sponsored shooters have represented their countries in various Olympic Games and won countless world shooting championships.  

RIO, a familiar name in Spain and Europe since 1896, was introduced to US shooters in 2002. With the opening of its state-of-the-art production plant in Marshall, Texas, in 2015 RIO Ammunition is now focused on the production and development of cartridges for the American shooter. RIO Ammunition is the US subsidiary of MAXAM, the worldwide leader in the development, manufacturing, and marketing of sporting and hunting shotgun cartridges. RIO's success is based on proprietary technological developments and a totally integrated production chain ranging from the manufacture of the main raw materials to the production of all the cartridge components (cases, primers, powder, wads and shot).
