I've built two .338 Lapuas, and learned a lot. I guess it really comes down to wether you are going to hunt with it, or bench shoot with it. Initially I built what I call a "tacti-cool-tank" that had a hefty fluted barrel .930, XLR chassis, Stiller-Tac action. It was 17lbs without scope. Carried it once, and decided ya know what, I'm not in the Army anymore, and sold it. That would have been an incredible bench rifle if I would have kept it. Second one is on a Northern Action (do not buy one), long (30")thin contour Lilja barrel .750 on an MDT LSS, it's 7.8lbs without scope. Not bad, good shooter, but only for hunting. The thin contour barrel heats up pretty quickly, and after 5-7 rounds starts to give up some consistency in the groups. Currently building a .338 Sherman Short on a Pierce action, and a .33 Nosler with carbon barrels for hunting. Will be utilizing Iota Krux lightweight stocks, and keeping the barrel under 26". Will see how they both pan out. I love the Lapua, ran into a fellow that hunts with one in Alaska, 20" barrel. He keeps his shots within 300 yards. My best brass consistency has been with Lapua brass. I was lucky enough to find a competition shooter that would sell me his once fired brass pretty cheaply. This year I'm going to experiment with Hammr bullets. I've had good luck with .300 Bergers, but some inconsistency with the 225 and 250 grain Factory Federal premiums past 500 yards.
