[QUOTE="Long Time Long Ranger, post: 460995, member: 505"] RDM416, Let us know how it shoots. I would love to have one of those some day. Kiwi, that Barret sounds like a great long range elk rifle to me. I would love to smack one with a 420 grain bullet at 3250. I think that is when I would start doing the mile thing during cow elk season. B23, During the 90's when the Lapua case came out me and several others tried every possible configuration of the Lapua imp. case trying to beat the old tried and true 338-378 wildcat that had set the standard for big 338's since the 70's. We could not do it. You might get a super fast lapua imp barrel and a super slow 338-378 barrel and make them equal. But on average the 338-378 wins that velocity battle every time.
