.17 HMR and MACHII

[Cossack]

Well I found one thing, you CAN sqfely fire the 17 HMR in a 22HMR..... although not very accurately. I put a new scope on my 22 WMR Striker, went to sight in and grabbed the 17's by mistake. They shot without a problem but in something more like a pattern....not a group. The cases did not rupture but were blow out to perfect 22 WMR size..... with a 17 stamp!
Based on that experience I'm not ready to conclude that you can't shoot a Mach 2 in a HMR or how accuracy will be affected. (Just read last night that you can safely shoot the 22 WRF in a 22 HMR).
