Did you happen to dial it back down to zero, recheck your 100yrd, then shoot from your MOAR reticle at 4.75 = 5 MOA instead of dailing it up? Seems to me either the scope is bad (Not Tracking) or shooter fatigue (all over the map with inconsistencies). Remember you shot a great 1.5" group at 400yrds then dialed down 3MOA but then went back up to 7MOA to shoot the same target? Its definitely not the Sig Kilo or the bullet projection 300win @ 3k muzzle.
Think you have loose scope mounts, 300 Win recoil (recheck- level, base/ring torque, and ring placement )Did you happen to dial it back down to zero, recheck your 100yrd, then shoot from your MOAR reticle at 4.75 = 5 MOA instead of dailing it up?
