Oh, sure. Mostly from reloading Lead Round Nose, but you can find non-jacketed commercial ammo.
Well, you used to be able. Now finding any 9mm/.40/.45 is tougher...
Also: That Rule may only be for their "Indoor Range", due to the type of backstop or an attempt to reduce injuries/damage from spalling.
LEAD only can have its own issues with "Splash" (Make sure you have good eye protection as well as hearing protection)
Outdoor range may not have the same Rule... (Check with a BoD member first)

Plus, you should find out if Copper-Plated or 'copper-washed' ammo is OK.
It is different than "Jacketed"...
