The only ranges may be in the Boy Scout Camp Catchalot, but I'm not sure if they're used. But otherwise you absolutely cannot discharge firearms anywhere in the park {outside of allowed hunting}.
There is a fair amount of archery/shotgun/primitive arms hunting in the park. Mostly in the fall/winter although there is some hunting allowed other parts of year. No hunting is allowed on Sundays.
No
Sure just dont get caught
There are shooting ranges and a junior rifle club. I'm not sure about the rules out side of the ranges I'd check with the ranger station for more information.
