Out of the 4 animals taken on rifle hunts I was a part of this fall all 4 were prone shots with rear support on un alerted game. 2 shots on bulls were at 507 and 518 yards, one after the other by my partner and I. Mine was first, 507 yards. One shot in the lungs that was fatal but he was on his feet so i sent another. He had started walking so that one ended up in his hind quarter, which took him off his feet and caused him to roll down the slope. Really kicked myself for that one, but the first shot was fatal so my wind call was good. It did, however, highlight to me the variable of unexpected animal movement. Second bull stepped out and my partner sent one round that went in the back of the shoulder just missing the bone, jellying the heart and taking him off his feet in under 15 seconds. These bulls were genuinely in a place that the option was shoot them from where we were or not shoot, there was no angle of approach with proper wind and vantage to close the distance without coming out 50 yards from them.
The second was my wife's deer, 335 yards with an estimated 12 mile an hour wind. I gave her a wind call and she executed the shot beautifully, double lung taking the top of the heart off and he was off his feet in 10 seconds or less.
Third was a late season cow hunt with partner from earlier. Open sage country in a heavily roaded unit. We glassed the herd and made it to the closest point that gave us a vantage without exposing ourselves, at 340 yards. Zero wind, dialed and made a perfect double lung.
Those shots could be interpreted as unethical to some, but I sleep well at night knowing that all animals were dead in 30 seconds or less and that adequate preparation was done. 500 yards is my self imposed limit unless the conditions are exceptionally and undoubtedly calm, or I am making follow ups on a wounded animal. The efficacy demonstrated by my hunting parties this year is head and shoulders more ethical than the days of old, shooting into running herds of elk driven from the timber, and that is a hill I will die on.
