There have been several different .17 caliber rifles- rimfire and centerfire. Right now, I am guessing that you mean the two most common .17 rimfires- the ,17 Mach 2, and the .17 HMR. The Mach 2 is basically a .22 Long rifle necked down to .17. The 17 HMR (Hornady Magnum Rimfire) is a .22 Magnum necked down to .17. It has more energy than the .17M2. They two cartridges DO NOT interchange. Ammo is more common for the .17 HMR. No experience with the M2, but the HMR is incredibly accurate at 100 yards.

Ruger makes the New Model Single Six in .17 HMR, Taurus makes the 17SS6 in .17 HMR, the S&W 647 is available in .17 HMR, the Taurus Tracker can be had in .17 HMR, Alexander Arms and Excel Arms both make semi auto .17 HMR pistols,
17 HMR and .17 Mach II are nice fast little rounds. The HMR is necked down from the .22 magnum the Mach II necked down from a .22 long rifle. They are nice target rounds and good for squirrels, rabbits, ground hogs and even coyote with a well placed shot if it's within 50 yards or longer distance for the .17 HMR. they would be good for raccoon if trapped or feral cats should the need arise. They could easily kill a 300 pound hog for butchering if shot behind the ear. They are little bullets, but very fast and still dangerous so be sure of your target and the region beyond.
In short, no. The .17 Mach 2 and the .17 Hornady Magnum Rimfire are two different cartridges- they just happen to both have a 17 in their names. Only use the caliber of ammo that is stamped on the rifle. When chambered in a .17 HMR rifle, the .17 M2 will either not fire at all, or will split the cartridge casing on firing. The HMR has a larger case diameter and length than the M2.
