I own a 338 Lapua. I was at a 1000 yard range in Eastern Ohio (Thunder Valley) and another shooter had a 408 Cheytac rifle made by the Cheytac firm. I looked like a mag length Remington 40x. I use Nightforce 8-32x56 on my 308 and a NF 5.5-22x56 on my 338 Lapua, I don't know what his scope was but it was clear, powerful, and BIG! He ask if I wanted to shoot it, I said sure. The muzzle brake was quite effective, it felt like a standard 308 Win. The bullets were turned solid bronze, ammo was about $14-16 each and came 104 rounds in a small waterproof suitcase. I wasn't allowed to shoot any other target, only the 600 and 1000 yard gong, because the bullets would punch holes in 1" plates out to 12-1400 yards. As I said it was easy to shoot and very accurate, but kind of boring to shoot at a 36" gong (3.5 MOA), I hit 1 MOA gongs at 1000 with my 308 regularly and if I don't hit, I'm right beside the 1/2 MOA gong (5"). Price: three and a half years the gun, scope, and 2 cases (208 rounds) of ammo was a little over $14,500.00. Advertised effective range 1.25 Miles, the Foreign Legion WO went a mile beyond that. Good shooting!
BTW, My 338 Lapua is a Savage 110 BA, about 5 years ago it cost, including my scope, around $4000-4500 and good factory ammo is $10. I have hit cigarette packs at 500 yards, The rifle should be able to hit that at 1000, I can't manage the recoil yet (maybe next season!)
