Police like you to start off with a 17hmr , because they don't ricochet like a 22 . Something worth remembering especially in this dry weather with rock hard ground. A mate got hold of some 22lr tracers, we shot some off at night. It was scary, I mean they go all over the place . If any of you 22 boys get hold of any try it , it will make you think a bit about what is behind and off to the side of your target .
I hate .22LR for that very reason. My friend once took a shot he shouldn't have - I was down range and out of sight albeit he knew I'd gone ahead and so shouldn't have been shooting.
