I am not saying people should pelt you with brass. That one actually surprises me is an issue.
Also as I wrote most, car, bike, gun guys are fine telling you about their pride and joy.
I am not much of talker to strangers, but I would not flabbergasted if stranger at range spoke to me. I am not your kid, only speaking when spoken too.
I don't shoot at a range. But I do work up loads. I didn't realize people doing so were rocket surgeons and shouldn't be distracted. I wouldn't speak when shooting. But if a guy was with his little gizmos I wouldn't think it was like he was writing down the cure to cancer. Especially since I am usually letting my barrels cool for awhile.
Again I don't shoot at ranges,but someone saying, oh how do you like that, or reloading gadget I have never seen before may garner a question. I never regarded this as asking a russian mobster his business.
