OK, so the gun is an older 20" Knight SR-25 with a 11.25" twist. Cases are LC, gentle prepping (trimmed, flash hole debured, shoulder bumped .003" in a Redding Full Length sizing die).
Primers seated with a Sinclair priming tool. Powder is VV N540, primers are Standard Remington. Bullet is a 180 SMK made for the Army Team back in the M14 days. Looks a lot like the 175 or 190.
Started with OCW, got a couple of good groups at around 2675 fps. Made up some 3 shot loadings around the sweet spots and went back to the range to zero in on a good load.
Many of the groups had 2 rounds touching, but the third would be ~2" away from the other 2. All powder charges were weighed on a balance beam. Gun has about 250 rounds through it.
Shooting with a bipod and a buttstock mono pod, with a US Optics scope at 17x.
If I had hair, I'd be pulling it out right now.
Ideas, anyone?
