They actually have three hour walls, floor, and ceilings, and the rest of the facility is sprinklered. So as long as the local AHJ is OK with it per 4.2.2, I think they are OK...
Seems like common sense not to put sprinklers where someone could shoot them out, but is there an exception that allows for non-sprinklered down-ranges? The shooters area is sprinklered, as is the rest of the building. Concrete slab and steel constructed building.
Thanks.
