Thankfully, I've not shot at any the Public/Govt ranges in over 10 years...
Before I moved down here I was a member of both ARPC and 67 Gun Club.
ARPC is a great club just further than I want/need to drive too shoot and much more expensive.
67 Gun club is pretty close to home. Much smaller, but much cheaper. I can still shoot Pistol, Shot Gun or Rifle. Rifle goes out too 300. Full Auto, SBRs, Cans, all OK as long as your not being an Idiot or unsafe.
Really their only dumb rule is you can't shoot Pistol Caliber Rifles on the Pistol range. EX, My Scorpion Evo, 9MM.
One can shoot it on the Pistol range all day (suppressed or not) as a Pistol. Put the But stock on it and it magically becomes a Rifle. I think its for the old guys who can't keep up on all the different HW and makes it easier to identify.
