With the successes that the 338 lapua has been achieving in Afghanistan, I read that the military is moving more towards this for medium/long-range anti-personnel and anti-materiel use over .300 and .50. The role of the 338 in long-range anti-personnel use is unquestionable, but I am wondering about the efficacy of that round for anti-materiel use. I am sure that all of the "special" loads are available (incendiary, armor-piercing, etc.), but what advantage would the 338 have over a .50 Barrett? I suppose the main advantage would be "luggability" but 338's are not lightweight. Nevertheless, any additional weight savings in the Afghan mountains has to be a blessing.
