I belong to a Chapter in the heart of one of the most liberal counties in the country in Montgomery County, MD. Excellent facility and it promotes all kinds of firearms related ativities. Range has a lot of rules, mostly for insurance reasons.
I think about the only firearm they do not allow is any firearm that fires 50 cal. BMG round. Many times I go the range and there no one, or practically no one, there during the week.
In order to use the range, new members had a long orientation session, followed by a check-out for different kinds of firearms as well as a written test. When I joined years ago, all range users were classified as Range Officers.
Other Chapters may different.
Of course, the IWLA is one of the oldest conservation organizations in the USA. My membership costs about $100.00 a year. Hard to beat that.
My Chapter also has all kinds of oher activities to raise money and get members together with dinners, bull roasts and other kinds of stuff.
My chapter has a large 100 yard covered rifle range with bench rests, large covered and uncovered 50 yard pistol range, big sheet range, and I think bow and arror range. Covers about 100 acres. Also has a very large Chapter house.
