Hi Guys

Trying to dial in my pea shooter, 200 yards, no wind was a balmy 9C out. My gear, .308 Mike Rock 700 remmy etc. Anyway what do you think? The two groups on the left of the target, the bullet is touching the lands, the right group is 10 thou off. Did these shots all within a half an hour, didn't clean the barrel until I got home. Got greedy on the upper left after 5 shots, lol. Still dealing with run-out. Is 3 thou too much? Components, lapua brass, CCI benchrest primers, Varget and 175gr SMK. Using CO-Axial press and Lee Collet die and Redding Comp Seating die. My goal is to get the best groups from 100 to 600 yards, (meters when on the mainland)

You may try goin up .2 to .3 gr as long as your not experiencing any pressure signs. Give RL15 a lookin at when you get some available. Have you chronied any of these loads? Your runout looks fine. I would also play a little more with your seating depth.

If your only shooting out to 600yds a 175gr projectile really isnt necessary. Give a 168amax whirl.
