Gotcha. An inaccurate rifle (or one that's just generally not enjoyable to shoot) is not going to be conducive to good, focused, productive practice.Solid advice. Part of this and why he has been shooting my 257 wby is because his 7-08 isn't extremely accurate (very short crack barrel). So I think a new rifle he likes and is an upgrade will further his interest in hunting and shooting.
I would for sure avoid brakes. My first set of hearing aids just arrived, due in large part as far as I can tell to shooting brakes rifles. Not many (but not zero) shots without ear pro while hunting, and also many for sure with just earbuds or the three row rubber around-the-neck plugs. Mostly good muffs and often doubled up though. It really doesn't take much exposure to them to cause damage. Mild loss in my right ear, upper end of moderate loss in the left. I'm 43 years old.
Shooting steel and watching impacts through the scope is so much more fun (and instant feedback for productive practice). Paper is very useful, but you're probably not going to be watching the holes appear in paper (and even if you are it doesn't tickle the lizard part of the brain in the same way). Adding steel at distance is something that will drive the enthusiasm for practice.
