This was developed as a way to practice fundamentals (marksmanship at speed, draws, and reloads) with limited time and ammunition. Individual drills are shot multiple times to provide actual training benefit rather than just serving as a test of current skill level.

The 99 Drill is a versatile and comprehensive shooting exercise designed to enhance a shooter's speed, accuracy, and consistency across multiple distances. The drill involves firing a total of 99 rounds at a single target from various distances—typically 7, 10, and 15 yards.

Either 4×6″ or 3×5″ cards can be used as targets. The 3×5 version is obviously significantly more difficult. All shots must be fired before the end of the PAR time; shots fired after the PAR count as misses.
