Check out the Mason Dixon Precision Rifle Series.
They run a beginner’s match every year (usually March-April) that’s a great place to start. You can also sign up for one of the regular matches and/or RO one of them if you’re not comfortable with shooting it. Everyone is super friendly and helpful, willing to lend gear, etc.
They run matches between New Holland RPC, Mayberry Fish & Game, and Mifflin County Sportsmen’s Association. Highly recommend coming and checking one out.
