Why This Ammo Dominates

The Sierra MatchKing bullet is renowned for its unrivaled accuracy, featuring tight manufacturing tolerances and an award-winning design that consistently delivers 0.5 MOA or better in quality rifles—making it a top choice for competitive champions. Built for long-range dominance, it boasts a muzzle velocity of 2,675 FPS and a high ballistic coefficient, allowing it to maintain supersonic speeds beyond 1,300 yards while outperforming lighter 6.5 Creedmoor loads in windy conditions. Its boxer-primed, annealed brass casings make it highly reloader-friendly, supporting 10 or more reloads and significantly lowering long-term shooting costs for high-volume users. The 142-grain bullet, combined with a boat-tail design, provides superior wind resistance—reducing wind deflection by 15–20% compared to standard 120–130 grain projectiles.

FAQs 

Is this ammo good for PRS competitions?

Absolutely. The MatchKing bullet and low SD/ES make it a top choice for PRS pros. Its non-magnetic construction also complies with NRL/NRA match rules.

Can I hunt deer with this 6.5 Creedmoor load?

Yes, but the OTM bullet prioritizes accuracy over expansion. For ethical kills, shot placement is critical—ideal for vitals shots under 400 yards.

What’s the real-world accuracy potential?

In a quality rifle (e.g., Bergara HMR, Tikka T3x), expect 0.3–0.7 MOA at 100 yards with proper shooter technique.

How does it compare to Hornady ELD Match?

Both are excellent, but the 142gr MatchKing has a higher BC (0.565 vs. 0.536) for better long-range performance. Hornady may offer slightly better terminal expansion for hunting.

Is the brass crimped or annealed?

Features annealed brass for longevity and non-crimped primers for easy reloading.
