In this case it may be the ammo. The limited experience I've had with the Remington 30-06 Reduced load was helping someone at the range get their bolt action sighted in with it. He was all over the paper. After cleaning his barrel, don't think he'd ever used powder solvent on it, I shot a 3 inch group at 100 yards. Then shot two of my Hornady 165 gr spbt hand loads through it and they were touching. The 30-06 reduced load is after all a 30-30 round in a 30-06 case ... 170 gr round nose bullet at 30-30 velocity.
