Need some advice/input. Today my hunting partner and I were shooting different 7mm Rem Mag rifles using Barnes VOR-TX 150gr boxed ammo. The guns were shooting sub MOA at 100, 200 & 300 yards. At 300 yards both guns in lead sleds were hitting 13 below point of aim with the scopes sighted in at 200 yards and 1.5 high at 100 yards. The problem is Barnes states that the drop at 300 yards should be 6.7 for a 200. That 6.7 is pretty consistent across all 7mm Rem Mag 150gr ammunition out there. The only way to get that type of drop in my ballistic calculator was to change the BC from .450 to .225 and lower the velocity to about 2750. Our rifles are 24 & 26 barrels respectively and it was not shooter error as we both had sub MOA groups at 300 yards. They were just twice as low as they should have been. Any thoughts would be nice
