If I was you, I might consider the 338RUM over the Lapua if you live in US. The RUM might be easier to find ammo and brass. The one advantage of the Lapua is you can get quality brass from both Lapua, and Norma, where 338RUM, quality brass is not an option. You get what you get. Shoot, I don't know. Either one will do the same thing. Brass for the 338RUM is almost 1/3 the price.
