So, what type of exercises should I use?
The type you used in the professional training you take before going thru your own training on the range.
And most ranges don't afford the same opportunities, like drawing, holstering, moving laterally, moving to cover, reloading etc. Indoor ranges often have restrictions on rapid fire, which is something you need to learn.
The main point is to continue GOOD training that you've learn from a good source without making up your own. Range time would be an EXTENSION of that.
