Good Luck! Take a Ferry Boat ride down south? Go in with some other shooters and make a big order and have it shipped on the barge, any sportsmans/shooters clubs, they may know a cheaper way.
I asked one of our stores and the manager ordered a half case of .223 along with the stores ammo order. I live on the lower Yukon R. and we pay scalppers prices for any ammo. I learned to reload. When I get into Anchorage I'll air frieght pounds of powder, plus the haz-mat fees(small arms, smokeless powder).
Well good luck,
