On the R8 if you are running it right, as you finish pushing the bolt home, your hand just continues forward as your fingers wrap around the grip and your thumb swings back over then after you pull the trigger, you release your fingers and pull your hand back catching the bolt knob as your hand goes by and puling it back.
If you practice some at doing it, it's a very fluid quick almost unbroken motion.
That being said, the mechanical motion your body has to do, as well as the way the standard stock is configured is optimized for a shooter that is operating the rifle standing up or kneeling or seated.
It is not all that well suited for someone in the American style of prone shooting, laying on a flat surface.
In a match with a lot of laying on the ground prone shooting, it might actually be slightly worse.
The rifle is purpose built for hunting where you are either trying to hit as many running animals as possible in a short moment of time when they burst from cover as you walk/wait or both, or for example you are stalking game or predators that may suddenly appear as you walk.
It also has many safety features built specifically around walking with a loaded rifle and stalking game and riding around in vehicles and dismounting and such. It's an exceptionally safe gun to hunt with, but for strictly shooting games, some of the automatic safety features could trip you up and cost you time.
