Make sure you keep the paperwork showing you took it into the country, so Customs doesn't think you may have purchased it in Canada. I don't ever remember having any sort of problem like that, but some young whipper-snapper in Customs could slow things down on your return if he had his panties in a wad for some reason.

If you're thinking of Mexico, I've never personally done it. You may want to ask Booger. I'm not sure if he took his own gun to Mexico or if he used one supplied by the outfitter. Damn, my memory is slipping, did he do that big dove hunt in Mexico or South America? It sucks getting old.
