I only heard rumors about the place; trying to confirm whether it actually existed or not.  

Supposedly there was an indoor range on Bel Aire road; it was upstairs in a building.  And it only allowed .22.

Anyone ever hear of it?  Fairly certain it is long gone, if it was ever there at all.

I could ask my friend about it, as we both grew up in Parkville and Carney.
His brother is in his late 60's, so he might remember.

I grew up around there.   No knowledge of this.

The National Guard Armory back in the day. Also, the Marine Reserve Center as I shot there with the Calvert Hall rifle team in the 80's.

Holy crap!  I shot on the McDonogh rifle team in the 80s - back when you were required to bring a gun to school  

Actually, the team guns were DCM loaners (maybe Winchester 52s?).  I shot at the AGC range too & my old coach lent me an Anschutz to use at school.

Problem was, the headmaster was a liberal, and of course, irrationally anti-gun.  So he personally called OSHA to come out and shut down the school indoor shooting range.  Our poor coach fought valiantly to keep the program alive for a year by cuting back to 3 times per week at the Catonsville NG armory range.  He also looked into air-guns, but predictably, the headmaster fought him every step of the way.  There is no rifle program anymore.

Shot against your school a few times. Plus, the Libby (?) match at Marriottsville. Use to ride the MTA bus with my rifle from Harford Rd to the Hall, try that today
