The meat damage tends to be the opposite of what your thinking, we see very little meat damage from our 338's!
Shot placement is the exact point a lot of us are trying to make, I'll argue shot placement all day long as apposed to trying to muscle your way through to some vitals BUT if your shooting in strong or variable winds you simply can not replace a big high BC bullet for helping you keep that shot placement where you need it. I've shot antelope at normal ranges with a big 338 simply because I needed every advantage possible to make a good clean kill in some harsh conditions, another day I'd just pop them with a 22-250.
Last season we were taking some elk out of a herd at a decent range, it was inside my range with my smaller cals but the wind was starting to die then gust as it does in the mountains here as the sun goes down so we pulled out the 338's and laid some elk down, ya we miss the wind a little but we knew we would and by how much and the 338 still kept us in the kill zone where a smaller cal would not have.
Your smith not being able to get a 338 to shoot only tells us he does not know how to build or load a 338 and instead of learning he'll just bad mouth them so he does not have to build one, it has ZERO to do with the 338 or Lapua case. I don't know anyone who shoots a 338 for groups at a 100 yards, a mile+ that's mostly what you'll see!! The last group I shot with a 338 Lapua AI at 1500 yards you could cover 4 rounds with your with the palm of your hand which the last time I checked was well under 5/8ths of an MOA!! I've watch Broz hold half moa or better with his Terminator well beyond 2000 yards, that is well under 5/8ths MOA.
You can actually have your cake and eat it to with a 338, I run the 300's from my RUM's at 2800 fps OR I run the 250 Berger at 3100 fps which is fast, flat and Thors hammer to boot!!

Very little meat damage in my limited experience. And I don't give a **** what it does at 100 yards because I know it's "Minute-of-kill zone". However, my 338-375 Ruger will shoot well under 1/2" at 100. Also shoots a 1" group at 300 and about a 2" at 500. Not too shabby for a 10 lb (scope, bipod, and sling included) hunting rifle with no muzzle brake. She's got some snort when the bullet takes off, but recoil is still manageable.
