Shipping it to Hawaii tends to be prohibitively expensive, unless you either are going thru CMP, or have a friend with a freight forwarder. CMP only does .30-06, .30 carbine, and .22, so it may not suit your needs.
As a retail customer, your ammo has to be shipped on a next-day basis. SOme silly regulation somewhere that makes it saer. And FedEx freight to Hawaii is not cheap, unless you are CMP.
