Just bought a Vanguard 6.5 and it’ll do way under sub MOA easily with Hornady 129 factory loads. One thing, you really need to check and make sure that the bedding screws are torqued to 35 in/lbs. Mine were way under-torqued from the factory. I despise non free floated barrels and Tupperware stocks, but this rifle is pretty amazing out of the box. My spouse reminded me tonight that I’m a pro at fixing things that aren’t broken. I’m really fighting the urge to restock this rifle. Your mileage may vary, but I’m pretty impressed with this Weatherby Vanguard.
