.17 HMR is a rimfire cartridge. The HMR stands for "Hornady Magnum Rimfire"
17 caliber rimfire
A 22 Magnum (or Winchester 22-WMR) is rimfire cartridge, same with 17HMR and the 22-WRF. <><><> The .22 Jet, which is a centerfire, was also known as the .22 Magnum Centerfire- but they are rather rare. Most .22 magnums will be, as he said right up there- rimfire. <><><> I forgot about the 22 Remington Jet. (also known as .22 Center Fire Magnum, or .22 CFM) Nice update, thanks.
Some are rimfire, some are centerfire. Depends on the design of the firearm.
No. The terms "rimfire" & "centerfire" should self-explain. On rimfire the priming compound is in the rim of the cartridge and on centerfire the primer with the priming compound is in the center of the cartridge.
Centerfire
A centerfire cartridge has the primer in the middle on the bottom side of the shell, where as the rimfire is the whole bottom.
Centrefire
No- it is neither centerfire nor rimfire, since it does not use cartridges.
32 long is a rimfire cartridge.
No, it's a rimfire round.
.17 is the caliber, HMR means "Hornady Magnum Rimfire".
To determine if your rifle is rimfire or centerfire, examine the cartridge it uses. Rimfire cartridges have the primer located in the rim of the cartridge case, while centerfire cartridges have the primer located in the center of the base. Additionally, rimfire rifles typically use smaller calibers, such as .22 LR, whereas centerfire rifles encompass a broader range of calibers and are generally used for higher-powered ammunition. If you're unsure, refer to the manufacturer’s specifications or markings on the rifle.
