Over the years we have had many international competitors shoot the match.
UK, Germany, Australia, South America.
We provide a letter inviting you to the match which you use to show the State Department. That allows you to bring your stuff. It requires a pretty good lead in like 6 months, but there never been a problem.
Outside of Massachusetts, we don't have the retarded firearm storage laws that most of the world seems to have. As for the ammo, maybe ship your reloads to one of the match organizers?
recently I've sended money to a Pennsylvania SH member to buy a used wooden lefty hunting (!) stock, and I've asked him FIRST if it could be done_ (stocks are unrestricted items in Italy,of course)_ this guy has later reported that the shipping from PA to Italy has been stopped, and the stock seized, by U.S. Custom_ If that's true, please, will pay real attention about REAL issues BEFORE any shipping _ good luck,anyway!
