The .17 PMC/Aguila or .17 High Standard is a rimfirecartridge formed by necking down the .22 Long Rifle casing to accept a .172" diameter bullet. This cartridge was developed in 2003 by firearms maker High Standard and ammunition maker Aguila and introduced in 2004. The introduction was ill timed, however, coming in the middle of the introduction of two major new .17 Rimfires from Hornady, which took over the .17 caliber rimfire market.
The .17 Aguila can be shot in a rifle that is chambered for .17 HM2.
