Yes, a standing rest is the correct way to shoot these rifles.

I believe the light English and European style bolt action rifles and single shots are best shot from a standing rest also. I think anything you can do to replicate an offhand shot by bringing the rest up to your standing position is the best. The rifles seem to group differently and shoot to a different point of aim if the shooter hunkers down on a benchrest.

A two to three inch group at a hundred yards off a standing rest and you are good to go.
