I have never ever - oops except once as mentioned ealier, by BA, had the actual round inspected.
That wasn't really an inspection either just a look out of curiosity by a guy that didn't know what a .308 was.
When I opened the carton to expose a .308 silver tipped bullet, the mini bus driver, a female from Jamaica, said "oh they look nice and would make nice ear rings " she then pointed out to all the other guys, Police, Security and ground staff, that the Pilot was the authority on what could be taken aboard and what couldn't, so a quick 'phone call solved the 'problem'
Originally when it was 'found' I was told that ammunition was not allowed on any aircraft no matter what.
All the other guys, all fourteen of them, had boarded with the same or similar ammo and packed the same way as me, naturally I didn't mention that !!
