I believe you're referring to the Hornady Magnum Rimfire cartridge. It is a 17 cal and should never be fired in a gun chambered for a .22. It is faster and more accurate than the standard .22. and is good for VERY small game, like gophers and ground squirels.
The HMR diet focuses on healthy weight loss as opposed to rapid weight loss. The initials stand for Health Management Resources.
.17 is the caliber, HMR means "Hornady Magnum Rimfire".
