All, thank you very much for your kind comments.
Rolf, the 170-metre neck shot was a bet, but I had no other option to harvest this one. By the way, there's nothing exceptional in this shot as our hunting rifles should all group shots in 5x5 cm at 200 metres. Assessing both firing distance and shooting angle are key elements to me, but this data is now provided by most modern range finders; a good rest is the other key element so I prefer not shooting if my rest is not good as I noticed that without a good rest I missed most of the time. Such long shots are not always the norm to me and this year I harvested 3 bucks at 80, 60 and 25 metres; situation commands!
