AGC Range Facilities
The AGC range facilities, located at the junction of Marriottsville Road and Wards Chapel Road in northwest Baltimore county (see Directions and Map), offer all Clubs' members, their families and guests a safe, maintained, and clean location to learn about, participate in, and enjoy the shooting sports year round. The AGC range facilities offer:
* A fifty point outdoor pistol range with covered firing line – firing at twenty five and fifty yards – equipped to handle NRA conventional pistol match competitions;
* A one hundred point outdoor, lighted, benchrest equipped range with covered firing line – firing at 25, 50, 75, and 100 yards;
* A ten point outdoor high power rifle range with covered firing line – firing at 200 yards – with military-style target frames and equipped to handle national match events;
* A four field, lighted, outdoor trap range with automatic and manual trap houses, as well as two portable Lincoln trap throwers;
* Messick Hall (located adjacent to the trap range) clubhouse/meeting hall, with kitchen and restrooms – used by many clubs for monthly meetings and social events; also used for indoor air rifle training for Juniors' Programs;
* Lower range house/meeting hall – with kitchen and restrooms (located at the 100 yard Barnes Range).
All of the AGC ranges are operated in an absolutely safe manner through the strict enforcement of Range Rules posted throughout the facilities and which all club members (of all AGC clubs) are indoctrinated upon joining.
The AGC range facility is open seven days a week – from 8:00 A.M. until dusk on weekdays and from 10:00 A.M. until dusk on weekends.
In addition to its availability to club members for unscheduled informal trap shooting (arranged through a Range Officer), scheduled club shoots, and seasonal club trap leagues, the AGC Trap Range is also open to the general public every Sunday from 12:00 noon until 4:00 P.M., and on Wednesday evenings from 6:00 P.M. until 9:00 P.M. for supervised trap shooting. There is a modest fee per round of trap, covering the cost of targets and the operation and maintenance of the trap equipment (AGC club members: $2.50 per round (25 targets); non-members: $3.50 per round).
