Jonson Arms was founded with precision a pillar of the company. The core of the Jonson line of precision cartridges is a scientifically conceived design incorporating the best features of those rounds in history which have proved to be exceptional.
We hope by building ammunition around these principles we can help you accomplish your goal of the most accurate firearm you can conceive. The principles of parallactic precision upon which Jonson designs are created were discovered by ballistics geniuses in the revolutionary days when smokeless powder changed the world. Jonson Factor rounds are designed for shooters who want the advantage of technology and the art of handloading to come together in a unique creation all their own.
Jonson Arms Labs provide tools to precision target shooters, long-range varmint and big game hunters who want to take advantage of twenty-first century technology and the secrets of the most efficient and accurate rounds in history.
