When I was at PG School in the '80's, there was a Carmel Gun Club range about a mile in from hiway 1 on Carmel Valley Road.
Membership in the club was very reasonable. Fond Memories.
That range has been developed and is now all houses, judging from Google maps.
Back then, I found out about the club and range by talking to the independent sporting goods shop owners in Seaside, Pacific Grove and Monterey.
There used to be a gunsmith in Monterey, but he hung up his apron a couple of years ago.
I recall he belonged to a club much further out in Carmel Valley which was very exclusive by all accounts.
See if del Valle Gunsmithing, 224A Reindollar Ave, Marina, CA 93933, Phone: 831-384-1911
can point you to a local club.
I wish you good hunting.
