[QUOTE="Dirt_Nap, post: 2902163, member: 51704"] New build. 300prc proof cf barrel on a defiance action Shooting 199gr hammer hunters About 110 fired so far. Awesome groups with 80gr of H1000. Started out consistently at about 3050fps. Hit the jump and I’m at 3100. Very consistent std deviation between shots. About 5fps. The weirdness is I can only get about 10 shots before the group opens up wildly. I’m talking 1.5” groups. While with a clean barrel I’m getting under 1/2” moa. Came back and cleaned and more copper fouling. Talked to proof and they said I shouldn’t be getting fouling that quick. They said they have guys that don’t clean their barrels for a few hundred rounds. Any ideas on what’s going on? [/QUOTE]
