Why I always get my 6NIA.
Direct experience:
I attempted to cross at Aden with bullets (not cartridges), legally purchased. I declared them when stopped by US customs. They refused my exit. No 6NIA in my possession at that moment. I then had my 6NIA sent to me electronically as I made my way to Coutts. I was not stopped on US side this time. They knew I was coming.
Canadian side could care less, beyond PAL.
My guess is that the Aden staff were shocked to see anyone approach and wondered how anyone but a local rancher knew where the damn crossing was.
With the items you listed I'd get them a 6NIA and the small stuff won't get a second look.
Good luck.
