Seen a lot of what you guys are talking about, including being shot at - and I'm not exactly innocent when it comes to a quick 'identifying' peek through the scope - and I imagine there ain't too many who haven't done that. And that despite me carrying little Nikon's around my neck - I already got the gun in my hands, a quick up and look - it's an entirely natural thing to do.
I've also seen a mate pick up an empty gun and put a shot through the chimney pot down the road - we become casual with something we do all the time - I was out chainsawing with bare feet yesterday - would never have done that years ago. I'll do that again because I got away with it last time.
I've known three people shoot themselves, one through the chest with a .303, he survived too - all of them did, and they were never quite so casual with a gun after that.
I've seen some pretty bad behaviour down the range too, nothing evil - more just dumb arsed carelessness and have wondered what these people are thinking - it's obviously how they act all the time with guns - bit scary.
For years now I've reckoned 'gun owners' need to to spend time every year down the NZDA range (or equivalent) doing supervised 'safety training' - or similar. I'm sharing the bush with these people and I want them to be less casual than I am with a gun.
