This bull was killed spot and stalk.  I kill almost all my bulls doing that.  I located this bull on the way to our spike camp location about 4 miles from the truck.  He had 22 cows.  We named him 320 bull.  A half asses attempt on way in pushed bull and cows up around ridge and my partner and I continued to our area and set camp.  That night he went after a nice 6x7 bull about 305 we think and I went back to look for this bull.  I located about 50 yards down from a very steep ridge with his cows and he was just rutting hard doing what bulls do in mid september.  I was going to come over the back side of ridge sneak over and get him, but 8 cows cam running from across the drainage and cut my path off.  Now the bull has 30 some cows.  It is late, I decidede to let them be not push them out and go after in morning.  
Next day Jake went his way, and I went back towards mr. 320. they had moved a bit from the night before, so I began going down that ridge they were on staying on.  Jake was bugling in a drainage locating a few bulls and doing this got my bull to bugle.  I came in quiet.  The bull bugled again after a few other bulls started bugling. from the night before the elk just went over the other side of ridge and were only about 150 yards from evening before.  I snuck to top of saddle and could see the tops of his antlers walking about 50 yards down from the ridge.  I backed up, nocked my arrow, eased to the top, they started to get nervous, and began walking towards timber.  I cow called to stop, he did, I put 40 yard pin where it needed and the rest is history.  he went like 150 hards, and fell another 80-100 yards tumbling and rolling before stopping in the shade and under a tree.  
This bull did not leave blood.  I found my arrow, pass through, and dry tracked him.  I saw where he started to fall.  I get down to bull and my heart stopped a bit when he lost most of his right side.  So I started up the hill and found the broken antlers.  Lucky!  Got Jake did some pics, and began boning out bull.  I shot him at 8am on the 17th and we had him in my cooler by noon the 18th.  
We headed back in and hunted till the 21st.  My buddy killed a nice bull on the afternoon of the 21st.  

His bull scores 297.  This bull bugled and he snuck in silent and shot him at 62 yards.  I stayed high on ridge not moving, doing so the bull didn't feel need to grab cows and leave.  I bugled every few minutes and Jake moved fast and quiet, located and killed his bull.  
It was a great hunt.  Jake and I just go where there is not many people.  Did hear wolves, never saw them, saw more elk in 2012, then I have in a while, more specifically, big bulls.  Saw a few in the 340+ range and just some toads.  Can't wait till next year
