The 5.6X52R (22 Savage High Power) is the European designation for the 22 Savage High Power, designed by Charles Newton for Arthur Savage's lever action in 1912. Based on the 25-35 case necked down, the 5.6X52R uses a heavy-for-caliber 71-grain .228-inch bullet at a modest 2790 fps. Unlike later .22-caliber centerfires the 5.6X52R was intended for deer-sized game and in its day was extremely controversial. Its rimmed case, however, is ideal for single-shot actions, and the European roe deer is much smaller than its American counterparts. The 22 Savage High-Power has been obsolete in America since before WWII, buts as the 5.6X52R it retains enough popularity in Europe that Norma continues to load it.
