As long as you have all the i's dotted and t's crossed for hunting, it ought to also cover "firearm sporting activities" at the range.
Not a lawyer, but it seems if you're worried about ITAR enforcement, having a valid, approved reason for accessing firearms while visiting ought to be sufficient.
Lots of discussion on this. I am not trying to be difficult and while I may have personal feelings on the "what's the big deal" aspect, I will stick with "do your own due diligence."
There is a route to obtain a Hawaii hunting permit entirely online if you are starting completely from scratch. Legit ways to avoid physical attendance in the Hawaii Hunters Ed course. While this does not equal permit to acquire, it covers legit hunting purposes.
Do out of staters, including Non-Resident Aliens want to come to Hawaii to take a course? Absolutely, I get a lot of inquiries. The biggest challenge for those who want to come to Hawaii and bring their own weapons is the 5-day rule, mag restrictions, and many worry about storage, sojourn or no sojourn topic when it comes to a hotel or residence with no safe. Plus our Foreign friends have additional challenges.
Even though there are guidelines for non-resident hunting and "target shooting" there is still ambiguity over what may constitute "training" and who as a trainer fits that category of go/no go under ITAR. When you look at the hoops and what if's, it is almost easier to submit the DSP-83. But then again it is costly, either way.
Seems the best bet is someone who does not fall under the "ITAR" restriction taking someone to the range and letting them "target shoot" your guns. For someone doing that too often, as in getting paid, you might garner too much attention from someone who might want to complain. For those genuinely conducting regular business within the industry, the "what if" scenarios just aren't worth it.
But then again "I hear" there are those finding ways to conduct business at KKHD which is entirely not my concern.
