pic shows ranges that SRGC uses, not including the skeet range.
KR3 sometimes has some steel silhouettes out beyond 500yds, target objects out at 1,000yds. or you pick out a light-colored rock way, way out there, and see how you do. look for the dirt splash. max caliber 50BMG.
KR4 is about 60yds max for posting a paper target stand. rifle & pistol combined. max caliber 7.62 rifle, .45 pistol. KR4 is probably the most frequently-used range for SRGC.
SRGC usage of CR1 has been scarce the last few years due to some Army reorganization, allocation & prioritization.
The Army has been allowing SRGC access to KR3 couple times a month, sometimes more, sometimes less, for the last couple years, depends on the Army training requirements which have priority over club use. And then it comes down to whether the club can come up with the qualified volunteers to staff the session.
As mentioned above, SRGC is open to Active Duty military, retired military, current and retired DOD civilians.
