Yep! And that's why I try to stick to the NATO-ish rounds.
I was thinking about the wording of the 2nd Amendment, . . . sometimes I wonder if they should have included the words "Because of" at the beginning. The reason why I say this is because the founding fathers were meaning for the people to defend against enemies, both foreign and domestic, . . . which included a tyranical goveernment coming into power AND making use of the "state militias", or volunteer armed forces, to do their bidding. So, it would be "Because of a well regulated Militia, being necessary to the security of a free State [to protect from foreign enemies], the right of the people to keep and bear Arms, shall not be infringed [to also help protect from foreign enemies, as well as domestic tyranny]."
Anyway, that's all I have to say on this topic, as it is taking a different direction from the OP.
I am unaware of my location's gun clubs requiring an NRA membership, but I have not attempted to join one, so I can't answer the OP with any specifics. Good topic.
