The truth is you could probably get away with mailing anything for quite a long time simply because the chances of it being detected is low. Thats not the same as it being legal, it just means you got away with it.
However, my opinion regarding the mailing of inert ammunition in the UK is that the authorities never considered the possibility that a bunch of geeks would want to do so. I would imagine US and other authorities are in much the same position.
As I understand it in UK the carriage of (live)ammunition is banned by the postal service’s internal rules and not law. However, the purchase of ammunition by any form of mail order is illegal unless you have a dealer to dealer transaction. There lies the problem, what is and what isn’t ammunition?
Most regulations just say ammunition they don’t say live ammunition. Does that mean inert ammunition is included or excluded? You then get into the situation of what I call creeping regulation where, because of uncertainty, people revert to an over cautious interpretation and by default the answer becomes no.
Also, because of the present hysteria regarding terrorism, any petty official who detects a potential anomoly is liable to hit the red button rather than just query it with you. Thats the real danger because once these things get going they tend to have no reverse gear.
Anyway Ray, if you should go to jail its not so bad. No bills to pay, three meals a day…
