So here are the results form the 105 Lapua loaded over Varget toward the upper end. The Wilson seating die made a big difference with the Scenars now grouping more similar to the Bergers at 200 yards. I seem to persist with the one flyer out of every five round group. Maybe it's me? But it seems unlikely I could pull a shot that consistently. It bugs me. The only one I'm sure of is the first shot at 26 grains as I was looking for the 1st CC barrel impact. It may be the brass as the new Starline brass is a full .012 shorter than my once fired brass. Or maybe its a mag issue? Next time out I'm going to shoot at plain white paper so I can see if it's the same number in the string that makes the flyer.
As QuickLoad does not have the Lapua projectiles in the data base I have been substituting the Nosler 105 gr RDF and the Hornady 105 gr 2524. So far the velocities track the Nosler well enough. I'm going with 26.2 grains of Varget for the bullet seating depth ladder as it nearly matches the QL velocity for the Nosler and it's a little less pressure than the 26.3 load with about the same group size.
