Sorry that some of you couldn't open the attachment. The bullet was a 130 grain GMX fired from my 24" barreled Rem 700 BDL SS, .270 Win, at about 50 yards.
I'd grunted the 130 lb. buck in and it passed quickly within 8 feet of my tree stand and stopped about 35 yards away, looking back toward me. The only shot I had was left-handed, but in the few seconds it took to brush the sling away from the trigger guard with my left hand, the buck saw me and took off low and fast, but straight-away.
Looking somewhat downward, the multi-x crosshairs quickly found the good spot directly behind the deer's shoulders and, in a flash, the rifle fired and the deer was somersaulting.
