Range testing

[Wis65x55]

I finally had the time to test the new chronograph today. The first load tested is a 260Remington model 7. 43.0gr IMR4350, 120gr bt WLR primer, nosler brass. 2668 fps muzzle velocity with a SD of 5.6 group size .344" at 100 yards! (no picture)
As for the 280 Remington:

Sounds as if the .260 is doing very well for a Model 7. That action isn't one of the stiffer actions available. You've done well, Keith. As for the .280, you're close to MOA and you have a decent standard deviation. Perhaps it is time to play with seating depth?

Looks good Keith. I think if you tweak the seating depth a little that'll be a heckuva good load. The speed looks excellent.
