One of the best practice tools that you can invest in is a timer. Any practice run can “feel” good, but unless you know how fast you were able to perform, this really tells you nothing about how that will translate into a match. Personally, I have had practice runs that felt really smooth and good, only to look at the timer to find out it was one of my slower runs. These speed drills also do not take a lot of ammo. You are trying to minimize gun handling mistakes, so single shot runs are fine.
By watching this video, you will gain some insight and tips for good drills to run and how to incorporate them into your training regimen.
