Pittsburgh, PA (Sept. 26, 2025) – Peterson Cartridge Co. of Pittsburgh, PA today announced the addition of the 22 ARC to its growing family of rifle casing calibers.

“After launching our 6 ARC casing, it was only natural to follow up with the 22 ARC,” stated Derek Peterson, president of Peterson Cartridge. “We heard the demand loud and clear – especially from predator hunters and gas-gun competitors looking for a high-performance option in this caliber. The 22 ARC gives them the consistency and precision they’ve been asking for.”

The 22 ARC is the 62^nd caliber in Peterson Cartridge’s lineup of calibers and the second in its ARC family.

“We built the 22 ARC using the same proven technology as our 6 ARC, which eliminates the common ‘belt’ or ‘bulge’ issues associated with the ARC calibers used in gas guns,” Peterson said. “There is growing interest in AR-type shooting competitions like the Geissele Gas Gun Series. PRS has a gas-gun division now. And the Peterson 22 ARCs are ideal for this.”

“We’re especially excited to connect with more predator hunters and competitive shooters. This round is built to deliver in both fields,” Peterson added. “You can find the Peterson 22 ARC brass at many dealers and distributors – or order direct at petersoncartridge.com.”
