I believe the .338 RUM is a better designed caliber than the Lapua. I think the Lapua gets some of its novelty because some armed forces started picking it up as a sniper round to supplement the .50, and a lighter option besides hauling around a .50. I believe the design of the .338 RUM allows for more precise headspacing, which will allow better accuracy. And plain and simple...look in a reloading handbook, which shouldnt be followed like a Bible, it is there for reference only, but it will show, out of the same barrel length, same bullet weight, the RUM is slightly to its supperior. Is the Lapua cool? Would I like to own one? Hell yes to both. But I am not made of money and can only afford to have one large caliber rifle, and I will choose the RUM. WAYYYYY cheaper to shoot, and way easier to find ammo, around my neck of the woods anyway.
