Sadly, CC license rejection is too big a risk to try such stuff - because you have to declare a rejection on many or most other states' applications - so everyone becomes concerned about things like exact wording. It's not even worth trying something cute as a matter of humor because there is more than the filing fee to lose.
That said, as Rob's successful use of "protection" shows, the processors of out-of-state NH applications haven't been pedantic and will approve a reasonable basis even if it isn't literally stated in the RSAs. But if you want to play it safe, use one of the "proper purposes" listed in RSA 159:6 - "Hunting, target shooting, or self-defense".
For my NH app. I use "all lawful purposes" and it was accepted.
