    .17 Hornady Magnum Rimfire, commonly known as the .17 HMR, is a rimfire rifle cartridge descended from the .22 Magnum. It was developed by necking down the .22 Magnum case to take a .17 caliber (4.5 mm) bullet. Commonly loaded with a 17 grain (1.1 g) bullet, it can deliver muzzle velocities in excess of 2550 ft/s (775 m/s)

    The .22 Long Rifle rimfire cartridge is a long established variety of ammunition, and in terms of units sold is still by far the most common in the world today. The cartridge is often referred to simply as .22 LR and various rifles, pistols, revolvers, and even some smoothbore shotguns have been manufactured in this caliber. It is occasionally referred to by its metric designation of 5.6x15mmR. The cartridge originated from the Flobert BB Cap of 1845 through the .22 Smith & Wesson cartridge of 1857, and was developed by the J. Stevens Arms & Tool Company in 1887 by combining the casing of the .22 Long with the 40 grain bullet of the .22 Extra Long. For many decades, it has been a very popular cartridge around the world. It is one of the few cartridges that are accepted by a large variety of rifles, as well as pistols. Virtually every manufacturer of cartridge firearms makes at least one model chambering it, and this has been true for more than a century. The .22 Long Rifle and related cartridges (.22 Short, .22 Long and .22 Extra Long) use a heeled bullet, which means that the bullet is the same diameter as the case, and has a narrower "heel" portion that fits in the case.

    Exactly what I thought some on the auction side are stating 22LR for this model rifle and 17HMR for the same model rifle on another auction. Had me wondering[:D]

    Many makers of rifles with the the same model number offer them in more then one caliber Example Remington model 700 has been offered in more then a dozen calibers. It is up to The buyer to know what caliber he wants in what makers firearm and what model.
