I'm in awe how many coherent arguments made by the gun community have skirted the draconian laws that our betters in state and federal regimes have implimented. It's a testament to the people who care outwitting the nanny-state who write shit they don't understand.

So.... maybe someone has thought about this one.....

My concerns here are local and state regulations.

Running off memory, I want to think that a necessary component of the definition of 'firearm' is that it use gunpowder (or maybe 'explosive charge', or something like that).

If you're shooting that Aquila Colibri, without gunpowder, is it still discharging a firearm? It's powered off the rimfire primer only. Does 'explosive charge' of the primer get defined by the state, or by the fed transportation guys, or someone else all together?

Maybe it's just a pipe dream, but if I can shoot that colibri stuff in a no shooting zone, it'd make for some fun.

For the purposes of this chapter, small arms ammunition, small arms ammunition primers, smokeless powder not exceeding fifty pounds, and black powder not exceeding five pounds shall not be defined as explosives, unless possessed or used for a purpose inconsistent with small arms use or other lawful purpose.
