Steve, some people will argue whether the .22 Hornet is a coyote cartridge. Many others argue about the .17Remington and so on. Heck, there are those that think anything less a .243 is too small for 'yotes.
Here's the way I look at it. The .17HMR IS GOING TO BE USED FOR COYOTES---regardless of whether or not it should just as the .22 Mag is. The .22 Mag is more consistent on coyotes but is still marginal. If the ammo makers can IMPROVE coyote performance by any substantial measure, they will have done us a favor. Lower velocity means nothing as far as I'm concerned so long as the bullet PERFORMANCE is there. After all, NO rim-fire should even be contemplated for over 100 yards on coyotes (and that includes the .22Mag). Alot of states that offer nighttime calling allow only rim-fires and shotguns. If a .17 user can get sufficient performance (.22Mag type performance) out of his Hummer due to better bullet performance, he'll have a more versatile rifle. The fact that it will be easier on small game is also a real plus!
One more thing, it would only make sense that the ammo makers would field test their new offering on the real thing or at the very least medium test if against the better .22Mag loads.
There would be no excuse for not doing so IMHO. ---- Mike
