The HSM 38551N Cowboy Action 38-55 Win 240 gr Round Nose Flat Point from HSM brings classic-big-bore performance to cowboy action shooters and recreational riflemen who want authentic ballistics in a modern load, offering a 240-grain round nose flat point that delivers approximately 1,325 fps muzzle velocity and about 936 ft-lbs of energy for reliable downrange performance with traditional lever guns and single-shot rifles. As part of HSMs Cowboy Action series, this ammunition matches the handling and trajectories aficionados expect for silhouette, target shooting, and period-style shoots while the brass casings and HazAir designation simplify range handling and storage. If youre running long-range iron sights or loading reduced-power loads for cowboy matches, the 38-55 Win profile provides manageable recoil and predictable points of impact that make follow-up shots and wind calls more consistent.
