Here's what I would suggest. .... check first on a STATE rifle association. Most are associated with the NRA and / or even the State Rep's for the NRA. Sometimes you can get combined memberships, or a discount on the State membership by joining the NRA thru them. Also, they will have State and local events that are NRA sanctioned, NRA certified instructors, etc. and ties you into that. And they typically have "youth' programs with firearms. It's not typically limited just to Rifles, at least ours isn't. They also help fight for State/Local pro-gun legislation, etc. as well a good resource for information on a local level.
Also , with many State associations you also automatically are a CMP member.... if you ever want to buy guns thru them. They do an Assoc membership with CMP, where all members are then considered members.
