At the last minute I grabbed one of my 6.8 SPC's out of the safe for our Mule Deer (WA State) opener yesterday. If I'm goin to hunt with a AR I usual shoot a 6.5 Grendel or a 6mm-6.8 SPC. This particular carbine shoots 1/2 MOA out to 400 yards with the factory Hornady 120gr SST loads. So I was very comfortable with it. As it would happen, I arrived in one of my spots, a two mile walk in about 30 min before daylight. Usualy the action is all over by 7:30 am, this morning the party didn't start until 8:45 am or so. I had about 40 head spooked out of a bedding area I knew was bellow me. They were all moving fast through the deep sage a little over 200 yards from me. I could see there were 5 legal bucks (3 points plus). It was hard trying to stay on them moveing that quick in and out of the tall sage. I finally started tracking the largest of the 5 bucks in my scope. He paused in a opening at 237 yards just long enough for me to send a 120gr SST. I heard the solid hit and he was out of sight. When I looked up from the scope deer were going everywhere! So I held tight until they all were over a ridge and out of sight. I waited another 20 min or so. Left all me gear where I was at and just took my carbine to see if I could find him. Found him 20 yards or so just outside of the sage I shot him in. The 120gr SST broke a rib on Impact, destroyed the lugs and exited. I was fairly impressed with the bullets performance.
