There have been several of us trying to do an indoor shooting/rental range in Helena for some years. Overall financing the range build (about 1 million for the equipment alone), and then approvals to get it done are the holdups. This too has been a dream of mine for years, especially since they closed the shooting range for the kids that was under the local Junior High. Good ventilation is a must, and without it you probably will not get approval for the range. You also may have to move from Missoula proper, and into the county just outside of town to get it done.
