Warning! Notes: 24-inch barrel; Norma .404 Jeffery cases; Federal 215 primers; instrumental velocities at fifteen feet converted to muzzle velocities; temperature 70 degrees Fahrenheit. These loads are considered maximum trouble-free loads for use under most hunting conditions with the components used in the test rifle. All rifles chambered for this wildcat cartridge will be of custom origin, and pressures with identical loads may vary, so initial handloads for other rifles should be four to five grains below the charges listed here.
