My outfitter had a pair in 2017 (now they are all banned) that had custom 30-378s and enough electronics to make a moon landing.

They passed up several good Mulies cause they were "too close".

Finally found on @700 yards and "ONLY" took 6 shots to kill it.

Guide put them on it by watching the snow splashes from the misses !

"Kaintuckie" windage and elevation.
