I was fooling around at the Range the other day and tried my Grendel at the 1000yd gong. My hold over was 36 minutes. I have the rifle topped with a 2.5-10 Vortex Viper XLR with no turrets and the reticle is only marked to 32 so I had to do some guessing. On the 3rd shot I found the gong and from then on it was dong, dong, dong. My rig is an Underground Tactical Arms, Bacon Maker. 18" Saturn barrel, CMC Trigger.
