17 Aguila

A recently introduced 17-caliber cartridge is known as the 17 Aguila. While the 17 Mach 2 utilizes the longer CCI Stinger case necked to hold a 0.172 caliber bullet, the 17 Aguila employs a 22 LR case of normal length. Powder capacity of the 17 Aguila is less than that of the 17 Mach 2 so a muzzle velocity of 1,850 ft/sec is produced with a 20-grain bullet (remaining velocity at 100 yards is 1,267 ft/ sec). However, bolt-action rifles and most autoloaders that fire 22 LR cartridges can be converted to 17 Aguila caliber simply by changing the barrels. Even though the 17 Aguila produces slightly lower velocity than the 17 HMR, the difference is not enough to make any practical difference in hunting use especially since the 17 Aguila uses a 20-grain bullet. Shots should be limited to somewhat shorter ranges with the 17 Aguila, but both are suitable for small game and small pests. The almost unknown 17 High Standard cartridge is apparently almost identical to the 17 Aguila.

Newest of the rimfire cartridges is the 17 Agiula, which is a 22 LR case necked to hold a 17 caliber bullet.
