I proly go to the range as many times in a month as he does all year. And I grew up shooting weekly at a club, my dad a dealer, reloader, shooter
This is a big part of the equation. Time at the range and not off the bench!
Bench shooting is good but thats mostly load checking. A little from field positions now and then is good practice. And it is like riding a bike IMHO. The skill never really goes away once youve got it down.
IMHO its more mental than mechanical.
Im picky on scope and gun fit and like lower magnification
