what is the deffirance in the two or ar they the same rifle?
just defferant ammo? thanks

I think the M2 is a necked down 22 long rifle, the way the HMR is a necked down 22 mag.

yep, i read somewhere, they came out with the mach 2 because of having difficulty cycling the 17 hmr through auto loaders.

so th hmr would have more power than the m2? thanks for the help

yes the HMR has more power, its like a 22lr vs a 22mag...

check out www.rimfirecental.com, they have all the information on both calibers that u could possibly need (or want)

Iver herd good things about the m2 , people liek it because it causes less meat damage them a hmr which is explosive on small game. if your not saving meat like me go for the HMR it's fun watching the explosive damage on gophers.
