The video says he is shooting a 7mm Rem Mag. I don't know what length Sauer uses for that, but some Co.s use a long/magnum action for it. The bolt throw may be too long to keep your head on that stock. Plus he's using his fingers to manipulate the bolt rather than the heal of his hand.
It's easy to keep your head down on a short action and most standard actions too, but magnum actions are too long for me to do that.
He's obviously a practiced & talented shooter, but if I was coaching him I'd change his bolt manipulation.
