Shooting skills vary hugely and very very much depends on how you learn and what you need. There is a world of difference between typical backwoods hunter who takes his shooting off hand at a buck jumping out of its bed in the middle of the woods as he works his way through. I know German hunters who are deadly on running boar or foxes, yet miss stationary deer that have stalked into on Scottish mountain from a prone position.
Previous generations could shoot with minimal aids, open sights and a pair of binoculars. Todays hunters seem incapable of shooting anything unless they are carry more computing power than a lunar rocket and a full bench rest to support the rifle.
Even in the UK there are huge differences between hunting muntjac in Southern Bluebell woods, to scottish Roe and red deer in highlands. Sika deer are another whole ball game.
And there is a world of difference between taking one shot that counts after a long day in the field - you are cold, wet, not in a perfect position and the only beast you have seen all day is very alert to your presence, but is perfectly positioned to shooting on a range where you have comfortable positions and plenty of time and many warm up shots.
I don’t think it really matters, as long as you appreciate there are differences, know your own skill levels and when it comes to live quarry, shoot within your own limits.
