At 600, the 41.8 gr load with the 139 Scenar grouped at 3.5". Four of the five shots grouped at 1.5", the fifth shot was low making the group the size it was. 3.5" was the group size and it was due to the one shot being low.
I'm going to shoot it at 1000 yards this week and try going up a little in .2 but 1/2 MOA of vertical is pretty good and I think I can live with it.
I came back from the range today and plugged all of the load info into QuickLoad. I've been reading about the "Optimal Barrel Time Concept". QuickLoad shows barrel exit time for the load you enter. The exit time happens to coincide with node 5 for a 26" barrel on the OBT table. It may work.
