Video shooting games can help with hand eye co-ordination as well as target acquisition and peripheral vision as you learn to seek out the target earlier which in your case allows you to mentally prepare for the next target as soon as you plink the last.
In unpopulated areas I like to tack gobs of paper targets to trees and "run the course" with a .22. Then run it backwards etc.
But I am not a very good/fast shooter. I settled on the slow=fast theory to offset my inadequacies...
