Great replies so far and I'd agree, it depends allot on the angle the bullet hits at, WHAT it hits....heck, even the temperature. Ground that would normally swallow a .22lr round in mild temps will often reject it when it's freezing outside. Again, the angle comes into play. I haven't had my 17M2 long enough to say, but I know I've had the odd ricochet with .22lr, .22WMR....but can't remember ever having one with my .17HMRs when I had them. Shot placement on small game with an HMR is critical if you want to eat what you shoot. Regardless, I wouldn't get too wrapped-up in the ricochet vs. .22lr argument since MISSING your target is the same as having a round bounce off and go astray. At that point, the bigger issue comes into play~as Winnipeg Toymaker touched-on. Your back-stop. As shooters, we need to be keenly aware of where our bullets end-up. So, in simple terms, don't take the shot if a "miss" sends the round somewhere it shouldn't be.
