Atomic Cowboy Action Ammunition 45 Colt 200 Grain Hard Cast Lead RNFP - Box of 50

Atomic Cowboy Action ammunition is purpose-built for shooters competing in or practicing for cowboy action shooting events. This 45 Colt load pairs a 200-grain hard cast lead round nose flat point (RNFP) bullet with a powder charge optimized for reliable function in single-action revolvers and lever-action rifles—the workhorses of the sport. Hard cast construction means the bullet won't deform or strip into the bore, even at the velocities typical of cowboy loads, making this a sensible choice for high-round-count practice sessions and match days alike.

What sets cowboy action ammo apart from general-purpose 45 Colt rounds is the attention to velocity and pressure curves that keep shooters in the power factor window required by most sanctioning bodies, while still delivering consistent accuracy. The flat point profile is designed to feed reliably through the actions these guns were born to use, and the hard cast lead resists leading in unlined barrels—a real issue when you're running full cases through vintage or reproduction iron.

Whether you're a regular on the SASS circuit or simply love shooting single-action revolvers the way they were meant to be shot, Atomic Cowboy Action delivers the kind of ammunition that lets you focus on technique and stage design rather than worrying about malfunctions or unexpected pressure surprises. Each box contains 50 rounds, making it practical for training or a day match without breaking the bank.
