.17 Mach 2 and .17 PMC

[XR7]

I see a website selling .17 PMC, says it can shoot through a .17 Mach 2.

does anyone have an experience with this?

what web site?

I dont advise it. The 17 PMC is close enough to chamber and fire but you will get a lot of split necks. I know 17 HM2 is tough to find but its never a good idea to shoot a cartridge in a chamber it wasnt designed for.

From what I have found they say it will work in a bolt action. That being said I would not use it in a semi-auto.
