Excellent!
I love my 6.8 loaded with the 120 SST's. My wife and son have both taken animals with it. It's a fantastic deer round. This weekend, my son tagged his doe with it in fact. Deer was quartering away headed left, round entered a little far back, but the it went through vitals, exited the ribs on far right side, went through the shoulder and lodged under the skin.
Congrats on a nice buck!
