Good info here, buried in a shitload of blahblahblah. It's pretty heavily moderated to keep zombies and politics talk to a minimum, sign up to use the search feature. Crappy info is usually called out as "one's opinion", and somtimes posters are a little too polite, but safety and shooting are the main objecticve.
The Firing Line is (
http://www.thefiringline.com/) is decent, from what I've seen. Decent, meaning there are folks who know what they're talking about who post regularly. I usually go there just following a link from some other place.
Both have been around for years and get hundreds of posts per day.
You can rarely find a gun forum without a good load of Constitutional Liberaterians bouncing around waving banners, and a light smattering of 15 year olds who shot their uncle's glock, and now pretend to be former Marine snipers.
There are a ton of model specific places, ar15.com
(aka ARFCOM), glocktalk, hipowersandhandguns, s&w boards, etc; where you can find the batshit crazy - mall ninja - operator trolls.
There is a 22 rimfire forum, the name escapes me, that had just a pantload of good info. EDIT TO ADD - rimfire central.
Have fun, take it all with a grain of salt, keep your muzzle pointed in a safe direction, and come back here and ask if you need to confirm anything.
