If you are zoomed in with the long range scope on the mosin, especially in the crouching stance (prone is fine, standing is alright but not great), the animation for the bolt action moves your view quite far immediately after you fire, making it very hard/impossible to see where your bullet landed.
If you are prone the animation is far less exaggerated so you can see where the shot lands with no problem (when standing it's not too bad) and adjust for future shots, it would be nice if this was also true when crouching.
If the animation is intended to move your view this much, it would be nice if it was a controlled event (e.g. press mouse1 once to fire shot, second time to chamber next round, third time to fire second shot. This way you can actually see where your first bullet lands so you can adjust your aim/zero).
