I owned a .338 Lapua (Savage 110 FCP) for about 96 hours. I bought it new from a dealer as an impulse buy because I got it for such a great deal (they were liquidating their entire Savage inventory). But I realized that the longest range I have available to shoot where I live is only 700 meters. I was doing that already with my .308. If I had a place to stretch out to 1000 meters or more, then I would have kept it. But I found the .308 to be challenging and thus fun, and to be honest, it was cheaper. And so for where I live, a .338 rifle capable of shooting a mile was unnecessary. So I sold it to a fellow CGN'er and he got an even BETTER deal than I did (I lost $200 on the transaction).
Anyways, my advice to you is ask where you're going to shoot it. If you're doing target shooting within 700 meters or less, then a cheaper round would be wise. But if you're hunting big game at a distance, or target shooting past 1km, then absolutely go for it, it looks like a good deal (assuming the seller can demonstrate that it actually shoots accurately).
