I believe that the .338 RCM or -06 fills a significant spot. Until someone brings out moderately priced commercial versions of the .338-06, the Ruger .338 RCM does nicely even though it requires one brand of brass. It remains a fact that very few over-.30 cartridges gain any popularity with recoil-shy Americans, out of the larger handful that are worthy. Remington has failed several times with the .350 mag and .35 Whelen, two cartridges with similar performance to their .338 counterparts.
