Shooting from 'left to right" is always more challenging for a right-handed shooter. My suggestion is to spend some time at the 27yard line or farther back ( Annie Oakley shooting) on a trap field concentrating on the left to right targets. This willl help you with proper gun speed and either pass through the target lead or a sustained lead, How to transition this to a rifle practice like the moving qualifying moose targets required in
Sweden or maybe Norway hopefully some on the campfire can help you with.
