Thread: .17 HMR blow up

"Current standards (SAAMI) show the pressures in PSI. For the 22 Long Rifle and Magnum (and the 17's), the allowable pressure is 24,000 PSI."

Interesting topic.
I had just assumed 17HMR was way more pressure than 22LR - that would result in the problems discussed here.
Not so. As the above quote from CCI rep.

I recently had to make the call for buying a new possum-rabbit gun.
I was very tempted to get a 17HMR, but in the end went with the proven 22LR (CZ457 Varmint) which has the quick-change barrel option, if required (22LR 22MAG 17HMR)
(.22LR CCI stingers come out of the barrel at 1550 fps) - If I was after some more exiting velocity.

Anyhow, I am really glad to have read this thread. I won't be getting a 17HMR in a hurry.
I am going to stick to my original plan, keep the CZ in .22LR for close subsonic work, and keep looking out for that rare beast, a .17 Hornet, and smack that ball right out of the park.
Cheers.
