Rio Ammunition, a company with a long and famous tradition dating back more than 100 years. is the only private company that manufactures all the essential components for its cartridges (hulls, primers, powders, wads, etc.). This, together with out notable work in R&D, enables us to achieve a level of efficiency which is without parallel, and the key to our success and leadership. In our constant quest for improvement and customer service, we not only produce 12 gauges shotshells - the size most asked for by hunters - but also offer a wide range of smaller gauge cartridges with identical precision and guarantee. This is loaded ammunition.
