Johnson between 1900-1902 to ensure reliable blowback action in the Model 1903.  It differs from other .22 cartridges by using a non-heeled bullet design and a special alloy to prevent fouling.  Ballistically similar to a standard velocity .22 Long Rifle, firing a 45-grain bullet at 1050 fps.  The Model 1903's tubular magazine holds 10 of these cartridges, loaded through the side of the buttstock.  Approximately 126,000 Model 1903 rifles were produced from 1903-1932, all chambered for this cartridge ****I CAN SEPARATE IF WANTED
