Pierce Develops New 10X Action for Big Magnum Cartridges

Pierce Engineering 10X Magnum Action

Pierce Engineering Ltd. recently revealed a new prototype action, a jumbo-sized receiver big enough to handle the CheyTacs and other very large magnums. This is good news for K02M and Extreme Long Range (ELR) Competitors, who favor mega-magnum cartridges pushing .375-caliber and larger bullets.

John Pierce says: “It’s been a long time coming, from design to prototype to testing. The Big 10 X is ready. This first test was in .300 Norma…next will be in .375 CheyTac.” Shown is a single-shot receiver. John adds that the “First repeater version should be completed next week. [This is a] dream come true.” This is one beefy action. Sources at Pierce say production versions should weigh roughly 3.75 pounds.
