Mary Arm Steel 38 Magnum is a high power magnum steel load built for serious waterfowl and big game wetland hunting — delivering heavy payload and strong knockdown performance when long range and extra penetration are needed.
Engineered as a steel specific magnum cartridge with robust wads and consistent load construction, it gives reliable patterns in tough conditions but should only be used in shotguns rated for steel and magnum chambers. Maximum recommended range: 45m.
