Moving at speed and hitting targets are separate skills — the Diamondback makes you do both at once. Four barrels form a diamond with a single target beyond the apex. You sprint the perimeter clockwise, engaging from each corner with alternating five-round body and one-round head strings, then loop back to the start, transition to your pistol mid-sprint, and close out the drill with a final six-round pistol engagement.
Set the target 10 yd (9 m) from the front barrel. Space the four barrels in a diamond with 10 yd (9 m) between each adjacent pair. Start at Barrel 1 (nearest the target) with the rifle at low ready. Rifle minimum is 12 rounds, pistol minimum is 6 — 18 total per rep. Benchmark hit factor for the rifle portion is 6.00 HF, scored A-zone or head only.
Track your times and hit factors separately for each barrel position. Most shooters lose accuracy at Barrels 2 and 4 where the angle to the target is sharpest and during the pistol transition. If your pistol string is weak, run the final sprint-and-transition segment as an isolated drill until the draw-on-the-move becomes automatic. Once every position scores clean, push the pace — the 51-Rifle rewards aggressive movement between barrels as much as precision at them.
Range Setup
Setup
1 target (IPSC, USPSA, or paper silhouette).
4 barrels arranged in a diamond shape, 10 yd (9 m) apart from one another.
Target is set 10 yd (9 m) from the front barrel (Barrel 1).
Rifle loaded with minimum 12 rounds.
Pistol holstered with minimum 6 rounds.
Start position: standing at Barrel 1, rifle at low ready, facing the target.
Scoring
18 rounds total per rep (12 rifle + 6 pistol).
Body shots scored A-zone only.
Head shots scored as hit or miss — no partial credit.
Benchmark: Rifle hit factor 6.00 HF.
Score each barrel position separately to identify weak angles.
Misses or shots outside A-zone count as failures for that position.
Scoring: Hit Factor (HF) = points ÷ time. USPSA target zones: A = 5, C = 3, D = 1, Miss = −10. Higher HF = better performance.
Tips
Focus on your drive steps and deceleration into each barrel — the time you save sprinting is lost if you overshoot the position and have to reset.
Progression
Add a par time once all hits are clean.
Run rifle-only (skip pistol phase) to isolate the movement pattern.
Run pistol-only from Barrel 4 sprint to isolate the transition.
Increase barrel spacing to 15 yd (14 m) for longer sprints.
Add a reload between Barrel 3 and Barrel 4.
Require all head shots — no body rounds.
