Cool video and I like the message but that first cartridge is not a .243, not sure what it was. I was first thinking .22 mag or .30 carbine but the proportions don't seem right and it has an odd mid-case crimp?
I thought the same thing but realized it was just the projectile sans the cartridge case. It's not obvious because they hold it so that you don't see the ends.
That was just about the stupidest thing I have ever seen. He keeps bloviating about gun safety while he twirls that rifle and muzzle sweeps everybody in the area. And he does this in every film I have ever seen him in. He is constantly pointing his guns at everything. Wayne has always been the Hollywood poster boy for careless gunhanding. The next time you watch a John Wayne film pay attention to his gun handling. It's almost unbelievable.
Well, didn't actually see him sweeping an audience of people, though I wondered the same thing. As far as Hollywood goes I never looked to them for reality in any venue including gun safety. John Wick anyone? Still like the Duke's movies.
