Found a brick of .22 today. Actually, several. At $40 a pop. I bought one and when my wife saw the $90 spend on ammo, she was less than pleased.
Story for anyone who may move to HI. I registered my weapons today. I cased them up, brought them took the Honolulu PD, filled out a few forms (request firm, permission slip for them to get my medical records, NICS style questionnaire) and paid for fingerprinting.
I also requested my permit to acquire a long gun. I can go back in 14 days to pick it up.
The whole process took maybe 2 hours or so. Not as bad as I expected.
Interesting fact about hawaii. You need a separate permit for a long gun vs a handgun. A handgun permit is good for a few days only, and must be requested each specific weapon. A long gun permit is good for a year and for as many guns as you want. And, for a state with so many loopholes, here's the weirdest thing. With these permits, you do not need to do an NICS check on purchase, as it's done when requesting the permit.
So in a few weeks I can get an SKS.
