We are forgetting some KEY ingredients to this whole test. The bullet, powder, primer, COAL, runout, case capacity, neck tension, etc etc. You take ANY target gun off the shelf and develop the perfect combination in ammo, top it off with a nightforce, behind a professional shooter and they will be able to make that shot with any target gun.
Savage, just like any company, offers a product line with a good, better, and best strategy. Them generalizing the accuracy of their "best" line consistant with their good and better line is a false statement. If they picked up the weather warrior and made that shot with some good ammo, I would be impressed.
Nice shooting though.
