Attend Orientation, Then Dive Right In!!
Chet,
BRAVO for being so safety conscious and wanting to comply with range rules and etiquette!
It sounds like you can't go ALONE to the range until attending orientation? If that's the case, it's likely that during orientation they will spend the majority of the time on the range rules and range etiquette. So, you'll have a good idea before you go about what you need to do. If you get to the range before orientation with a member, they will help you comply with the range rules.
At the ranges I go to, general rules are firearms unloaded with action open (if possible) until you take your spot along the line; keep firearms pointed downrange when getting set up (assuming shooters aren't downrange checking targets); no rapid firing; and range master calls out when range is hot and cold. When range is cold between firing sessions, firearms are pointed downrange with actions open and chamber clear.
I live in the People's Republic of Maryland, so I don't know if that affects our range rules - we can't have magazines with more than 10 rounds if I recall correctly, and maybe some of you in other states can do rapid fire.....
After I get my hunting rifle sighted in (Win Model 70 30-06), I spend most of my time placing three shots as fast as I can into a 6" paper plate at 100 yards and a 9" paper plate at 200, from offhand, kneeling, and sitting positions (I only do offhand practice at 100 yards). The last time I was at the range, the woman in the next lane with her husband asked him if I was a police sniper - she wasn't checking my targets, just saw me shooting scoped bolt-action fairly rapidly and wondered who would need to do that.
Go on out, Chet - you'll make friends quickly, and the range masters are always willing to help new shooters and members!
Michael
