I'm in frustrated mode as my .300 RUM on a Remington 700 is 1.5 MOA at best. My smith is trying to convince me that a Kreiger barrel (or the like) in at least a #5 contour is the place to start. This is a hunting rifle, so I don't relish the idea of adding another 1.5 lbs to the already medium heavy setup. How does H-S deliver guaranteed .5 MOA accuracy out of superlight rifles with 22" tubes? I'm shooting a pillar bedded, free floated, McMillan stocked, lapped lugs and re-crowned barrel with a Zeiss 6.5x20. Trigger has been worked. Factory 180 gr Sciroccos.
