Another option..... is the "free" range at Sherburne WMA. The rifle range is 25,50, 75, 100 yds and a covered shooting area. The range does get fairly busy in the fall before hunting season.
Pistol range is nice and hardly ever used. There is also a skeet/trap range that I think you call before using it......337 556-2251
The shoot range is located about 45 minutes west of Baton Rouge. It is about 15 miles north of I-10.
Also..... in the eastern part of the state....
