.17 PMC/Aguila

The .17 PMC/Aguila or .17 High Standard is a rimfire cartridge 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.
