I'll approach the question from a "performance for cost" standpoint. The .22 costs about $4.50 a box of 50 and travels at 1100 to1300 feet per second. It is a decent round out to 75 yards but then, it begins to have considerable issues with gravity. The .17 Mach 2, so named because it travels at twice the speed of sound "Mach"2.(approximately 2100 fps). It is a .22 Stinger case necked down to accept a .17 projectile. This ammo also costs about $4.60 a box or 2,000 rounds for about $185.00. The .17 HMR (Hornady Magnum Round) is a .22 Magnum cartridge necked down to accept the same .17 projectile. It travels 300 fps faster for $12.00 a box of 50. I have found NO appreciable differences in 300fps! Especially for an increase of $7.50 per box ! Both rounds are excellent performers out to 120 yards. Sure, I have hit birds out to 250 yards. But there is a LOT of hold-over. I have killed skunks, possums , raccoons and squirrels out to 125 yards with the Mach 2. It is a pleasant round, not requiring ear plugs, but the HMR does ! The HMR is LOUD. If you are shooting coyotes, move up to a .223 (which cost the same as the HMR)
