What’s the cutoff between small arms ammunition and “large caliber?” Is a 700 N.E. a “large caliber?” A 20mm, or 40mm MBA gyrojet? You see where I’m going here.
It’s your forum and you can obviously make whatever rules you want. I’ll read them and abide by them if I choose to participate, which, based on what I’ve seen, I think I’d like to do.
But what’s the point? What possible harm does a photograph of an unusual live artillery round do? And what possible difference does it make whether the item pictured is legal to own in my country? My submission might be a photograph of an interesting round of Soviet artillery, such as was used for their cloud-seeding experiments and that most cartridge collectors don’t even know about. Just because I can’t legally own a certain quantity of high explosive, or an atomic bomb, doesn’t mean that I don’t have some great pictures of these that other collectors might be interested in (the inventor of the gyrojet was a key member of the WWII Manhattan Project staff at Los Alamos).
Are we really at the point where a picture of something not politically correct is verboten? I hope not. But as I said, it’s your site and I’ll abide by your rules.
