What specific NFPA code addresses these places...
NFPA 101, Life Safety Code has the requirements for new construction of buildings. Looks like you are for the requirements of extinguishing systems by the tag of your posting. If the range is a free-standing building you would either classify the building as new assembly occupancies or a new business occupancies. Assembly occupancies require two features. First, at least 50 people must be present and, second, they must be gathered for some function such as eating, drinking, amusement, worship, deliberation, awaiting transportation, or entertainment. If not, the classification should be new business occupancies.
Automatic sprinkler system requirements will be found in subsection _.1.6 and/or _.3.5 of the NFPA 101 occupancy chapters. If required by the occupancy chapter, the fundamental requirements are in Section 9.7. The design standards are referenced by the occupancy chapter and referenced in Section 220.127.116.11.
The IBC may limit the building area based on the occupancy group, construction Type (fire resistance) of the building structure and installation of an automatic sprinkler system.
I can not go further into the code requirements with the information provided.
I am looking specifically looking for anything related to Fire sprinklers- inside the Shooting ranges....The concern is that a stray bullet might hit the pipes or a sprinkler head. Can the sprinklers be omitted if the entire space is built with 3 hr. fire rated concrete walls and non-combustible Trusses-Joists?....
Looks like you have a building or life safety code that requires an automatic sprinkler system. Can you tell me the code section and edition?
The code used here in Gilbert, AZ is the 2012-IFC ( international Fire Code) chapter 9

The code they use here in Gilbert, AZ is the 2012 IFC ( International Fire Code) Chapter 9
Looks like the occupancy classification for this building or portion thereof may be Group A-3 assembly.
Using that occupancy in Chapter 9 of the 2012 IFC it appears this section applies:
It appears from the information you provided the shooting range is a fire area because of the 3 hour fire resistant construction. Maybe others didn't look at it this way. I think differently.
Your question: Can the sprinklers be omitted if the entire space is built with 3 hr. fire rated concrete walls and non-combustible Trusses-Joists?...
Unless the fire area for the shooting range has a condition where one the of the requirements of Section 903.2.1.3 exists, I would with some certainty suggest that the range would not require a sprinkler system.
I think you hit the bulls eye…..!
Most do a scissor ceiling and install the sprinklers where they will not be hit
Like this type ceiling
Or just do a flat and install concealed sprinklers
They do burn!!!
This is exactly what I’m faced with!...
A flat ceiling won’t do!
The other issue is...the slanted sound panels will be obstructions to the spray pattern of upright sprinklers.

For flat use concealed
For the other the sprinklers just have to follow obstruction rules. There may be a few more sprinklers than normal.
It can be done either way and have seen it done either way.
I am thinking you only need NFPA 13 and someone decide on the actual ceiling to be used.
I was thinking to provide a line of sprinkler protection at the entry ways, and all across that aisle.....And omit sprinklers in the actual shooting lanes since there is no storage, or actual occupancy.
Would this be possible?....I know it will be an AHJ call, but it's worth to try.
I did not want to bring up that option.
Might depend on the set up.
If people stand at the back onlyband shoot, I can see that as a possibilty.
If they can stand anywhere on the range, including down range, I would say no, sprinkle entire area.
Thanks for your advice. Much appreciated!
Have to look I thought in there I coded there was a provision not to sprinkle certain sports use areas.
