So some people don't have the consideration to pick up their 7.62x39 steel casings, the same seems to happen with .22 brass. But I don't see what that has to do with the recent action against rifle shooting. Unless I'm mis-understanding and in fact my .223/.308 are not under this military ammo category and I'm free to shoot my Tavor with impunity. Though the bulletin still has me at the rifle sighting statement as I am not sighting in my rifle, I will be shooting it.
As for my encounter with the older gentleman, I did not allow him to dictate terms to me (If I allowed random guys to dictate what I should or shouldn't be shooting I'd have stopped bringing my Tavor out there long ago), he referenced the latest bulletin which I had not yet read which is why I gave him the benefit of the doubt that there was some legitimacy to what he was saying. And as it turns out, though the bulletin doesn't say anything about automatics, the message is the same, the 100m is for sighting in rifles. As this is not a rifle club, it is a PISTOL club.
Also the bulletin clearly states that "The silhouette range was approved for the rifle calibers so that members could sight in their hunting rifles". Though I do know what you're talking about with regard to the other ranges that are approved for rifles shooting pistol calibers.
That's a good idea about the cameras, hopefully it'll deter the negligent shooters. That being said, it seems the solution to negligent pistol shooters is installing cameras, so... it would make sense to apply the same solution to negligent rifle shooters would it not?
