It very well might be the bedding. Is the barrel free-floated, or does it have a "tip hump" that presses on the barrel? My experience is that just is that Weatherbys of all models shoot more consistently when the barrels are free-floated--and many aren't from the factory.
The torque isn't a big deal, but the relatively light recommendation of 35 inch-pounds can indicate the stock might flex too much with more torque.
