There are some good points made in this article:

However, this opening statement is odd.

Once I fired three consecutive bullets into a 4-inch circle at 1,000 yards and fancied myself quite the marksman. Then I missed a bull moose at 150 yards. Apparently, shooting targets isn’t the same as shooting game.

Shooting with extreme precision, even when done at long range, is certainly challenging and helps develop a refined shot process but it probably does not incorporate a number of important elements useful in a field environment. The problem is not that shooting targets is different than shooting game, it’s that many (most?) hunters put little or no effort into making their range shooting at targets into an exercise that more closely mimics their field shooting at game. Sort of like a person participating in their first 5K Run claiming that gym time is useless while ignoring the fact their exercise plan included no running before the race.

The correct assessment here is range exercises that don’t work field shooting parameters into the mix are not like shooting game.
