It seems All those 6mm cartridges favored by the PRS shooters are some of the most inherently accurate cartridges made today. I bought an off the rack savage 6arc, dumped 27 grains of Varget, topped with a 108gr Berger, sparked with a Fed match primer in Hornady brass salvaged from hornady match ammo and shot 1/4 to 1/2 minute groups out to 700 yds. i shot my first match a few weeks ago and got trounced by a friend of mine shooting a home made Remage using out of the box hornady ELDM factory ammo. He even headspaced his rifle build with 3 pieces of fired brass he borrowed from me.
