Starting a range/club from scratch is the ONLY answer.
Two times now, I've seen full-auto friendly clubs change the MG policy after "Word got out" that they allowed full-auto.
It took 1 year for Hamburg Rifle & Pistol to do away with MG's alltogether. They also voted out all the high ranking officials of the club that were full auto friendly.
Millcreek Rod & Gun only lasted a few months... Same deal there... When the Elmer Fudd's of the club realized that nearly 50% of the club membership had MG's, they voted to ban them.
These clubs need to be taken over from the inside out, or a whole new club needs to be established.
It really shouldn't be that complicated to do. Deer hunters do it all the time when they pool their resources to buy land and build a hunting camp.
Personally, I'd almost rather see a group of us build a lodge or cabin, that also has range facilities. That way, it could be a "time-share" or family oriented facility when not being used for dumping lead downrange...Those of us that hunt, can also use it during hunting season...
You get 10 guys that each contribute $10k, and you have lots of options...
