So this is strictly non-magnum handgun for the informal shoot, and rifles for the informal-formal bullseye.

Do you operate by permissive or restrictive rules? Like you say 9mm carbines are OK, but what about subsonic rounds that would be less concussive than 9mm, like a 45ACP carbine?

I'm planning on coming out, just trying to get a better lay of the what's-what and what ammo I need to make sure I have.
