A good way to see what the culture will be like is just to go to the website for each and look up the campus organizations.
Shooting club = good
No shooting club = bad
Business incubators = good
La Raza group = bad
Communists/socialist societies = very bad
Anti-gun group and no shooting club = VERY bad.
You can't neccessarially rely on the organized club system to accurately represent what goes on at a given campus. A club can be on the books and have only a few members. There can also be a whole lot going on outside of the organized clubs-some groups don't organize because the paperwork just isn't worth it.
My undergrad didn't have a shooting club, but I went shooting a good bit with the local "townies".
