I believe you are wrong as it pertains to the ops question. The item quote below is from the range complex on their facebook page dated August 21 pf this year. Take special note of the part I bolded.


Shooters!!!! Great news for all you 300 magnum and .338 magnum shooters, we've been granted clearance to fire these caliber rifles at the CMSC. At this point, we'll allow you to shoot up to 100 yards on paper. By next Friday, 28 August, we'll have the 300 yard target line ready. Please do NOT ask if you can shoot the steel targets past 300 as this will never be allowed!
