Only trouble I have had was crossing at Sumas. I was warned before I crossed there, but I ignored the warning since it was a simple crossing when I've been up fishing in Chilliwak. Not sure if the Game check people there hate hunters or are just incompetent or both. Luckily one of the guys who warned me gave me a card with the local senior gamie's cell number. I called him at the first sign of trouble and he was there within moments and set them straight dang quick. Still took me more than an hour to cross!
Oroville and Kingsgate crossing went super smooth and quick. Gave them my paperwork showed them the animals and they said, "Yep, looks like one of those to me. Have a nice day!" Even when a guide forgot to give me the proper forms before I left the Kingsgate crossing game check got me fixed and taken care of in about ten minutes.
You will pay a fee to register your rifles on your way up. I think it was 20 dollars or something close to that. But I've never had a fee coming back across into the states. I think I did have to pay a fee to get my paperwork and horns plugged and sealed in NWT before boarding the plane to Edmonton. Wasn't much though. It hurt worse to watch them drill holes in my sheep horns
