Gun safety terminology?

This probably isn't an issue for the average foreigner in China but I thought I'd ask. My father in-law is visiting my wife and I here in Virginia, and I thought it might be fun to act like true Virginians and visit the firing range.

Anyway,since I may have to be the translator I was wondering if anyone knew common/basic terminology or common phrases about guns, gun safety, targets, types of guns (rifles, pistols, shotguns,etc.)?
