Ok maybe obsolite is not the right word. sorry about that,

IF the .17m2 does what they say in the articles on it

shoots flat to 100
cheaper ammo than the .17hmr
shoots out of guns chambered for .22lr with only a barrel change

It may make the HMR like the .22mag - good, just not as popular.

I'm thinking of the price down in the $3 per box with "plinking" bullets would make guys like me go for the m2 vs the HMR
