Diana started business in 1974 but only a few years later, with the advent of plastics, there was a radical change in the production of wads.

Despite this, Diana decided to continue production of traditional wads, making a decision that is still the foundation of its success. Not only, the company also plans and contructs its own production line.

Thanks to these decisions, Diana avails of technologically exclusive systems giving a traditional product the top quality required of modern sports cartridges.

Nowadays Diana supplies the best European brands.
