Ok.
To all of you saying put it in your check baggage and shouldn't or won't have a problem......
It's a roll of the proverbial dice....on my first trip I brought back my souvenir brass in my check baggage and had no problem. My check baggage and ammo box wasn't checked, and I declared to the SAPS officer that all ammo was spent...not exactly a lie, but not the whole truth per se. What ammo wasn't shot was....sort of, part of, my PH's gratuities, in addition to his monetary tip. (Thus spent).
On my second trip, I met and became friends with some fellow Ohioans who rented their weapons and ammo from their PH, who I also became friends with on my first trip.
Both trips I brought my own rifle and ammo. On returning home I again brought back my own souvenir brass and as a favor and precaution I also brought back the souvenir brass of my fellow Ohioans. After all I had my weapon and ammo permit and shouldn't have any problems as the souvenir (spent) brass is of the same caliber.
Since my check bag with my ammo lock box was already packed, I just tossed my friends souvenir spent brass (4 or 5 pieces), into my luggage.
SAPS, checked my baggage, ammo box (of course we all know the routine with "the book"), no problems......until they found the loose spent brass I had just tossed in my bag. After about 10 minutes of trying to explain why it wasn't in the ammo box, and being made aware of the penalty of my error and another few moments of debate amongst the 2 SAPS officers, I was allowed to continue on my way, followed by one of the SAPS officers past the office door. At this point I was chastise once again of my error and how they were being friendly about this incident, and they were putting their employment at risk by allowing me to proceed...one in such a situation should be well aware of what is being implied.
I pledge my gratitude to their such kindness, and remanded the officer a friendly handshake and R40.
Just saying, be aware, there could be consequences to having loose (spent) brass in your luggage, especially if you didn't bring it with you.
Will I bring back spent souvenir brass in the future, Heck yeah! However, it won't just be hap hazardly tossed loose in my check baggage.
