50th Anniversary

Celebrating 50 Years of American Ammunition Excellence

In 1968, Bill and Catherine Campbell embarked on a journey that would help shape the modern ammunition industry. Operating from a small Montana town with a commitment to quality and craftsmanship, they founded what would eventually become HSM Ammunition.

Initially serving the law enforcement community, HSM quickly earned a reputation for producing dependable, accurate ammunition. Through customer recommendations and word-of-mouth referrals, demand grew rapidly. Agencies across the country recognized the performance and consistency of HSM products, helping transform a small family operation into a nationally respected ammunition manufacturer.

As the company expanded through the decades, so did its product offerings. New calibers were introduced, manufacturing capabilities advanced, and HSM broadened its reach across virtually every segment of the shooting sports industry. Strategic partnerships with respected component manufacturers helped further elevate product performance and reinforce HSM’s commitment to excellence.
