17 cal rimfires

perry shooter

I know there are 2 different 17Cal rim fire one based on the 22 Winchester Mag =17HMR and one based on the 22long rifle =17Mach II but what is a 17 PMC ? I think it may also be based on the 22 Long rifle but what 17 based on the 22 Long Rifle seems to be the easier to find ammo for I want to change barreels on ruger 77/22 Thanks Karl

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.

Assuming your 10/22 is a .22LR, going to the 17 based on the same round should be a simple barrel switch. I think if you go with the 17HMR, and are not already working with the Mag. action, you may need a heavier bolt. Not sure if other mods are needed.

The .17M2 is based on the .22 Stinger length case which is a little longer than the .22 LR. The .17 High Standard/Aguila is based on the .22 LR case. The oriiginal High Standard was playing around with a .17 cartridge in the 1940's. There are a coupple of related articles on my website at:

Thanks John I saw the 17 barrels that Bob S. had at Perry a few years ago but never got excited about a 17 pistol. I can't hold good enough to take advanage of the 17 in a pistol I shoot one handed BULLS_EYE and a 17 is not legal[:(] . However I thought I might want to try in a rifle. and having a 77/22 barrel changes would be easy [:p]I just wanted to get one chambered in a cartridge that I would be able to get ammo for in years to come[:D]I still have a 8 Track, BetaMax, and 5 MM Remington [V]. I did make the Mayleigh cup with a used $85.00 High Standard when the rest were shooting Hammerlie 208's.

Perry,

High Standard was selling .17 barrels for their round well before teh ammunition became available. Some of our club members bought the .17 barrels or pistols and then could not use them for well over a year. The ammunition finally became availale over a yeat late.

If you don't want another 8-track I would bet on .17M2. A lot more manufacurers are chambering their guns in that round than the .17 HS round.

Must have been late. Maybe my glasses were foggy. 77/22 different story obviously. Have fun and report back on how it goes. Personally I haven't yet found the motivation to go the tiny barrel hole.

JMHO, but the Agulia version is a sexier looking cartridge than the Hornady version.

Hey Tailgunner I hope Cartridges are not like sexier looking women, they all get Old, Fat, And Ugly so it's best if you marry one that is rich wish I had known that 40 years ago.
