HSM .223 Remington ammunition (part no. 22311N) loads a 77-grain Sierra MatchKing Boat Tail Hollow Point for competitive and long-range shooters chasing tighter groups. HSM hand-loads short production runs using premium bullets from Hornady, Sierra, and Berger rather than mass-producing generic projectiles. The consistent, concentric jacket and boat tail base are built for the accuracy competitive shooters demand, not for hunting expansion. Brass-cased and 50 to a box, it is built to feed reliably through bolt guns and semi-autos chambered for the cartridge. In our rifle ammunition lineup, this .223 Remington loading is a confirmed, dependable choice worth adding to the cart.

Key Specifications

• The chambering is .223 Remington, a mild-recoiling, extremely common AR-platform cartridge with the widest factory ammunition selection of any modern rifle round.
• The bullet weighs 77 grains, setting the balance of velocity and downrange energy this load is tuned for.
• The bullet is a Sierra MatchKing Boat Tail Hollow Point, the projectile HSM chose to load behind .223 Remington.
• The consistent, concentric jacket and boat tail base are built for the accuracy competitive shooters demand, not for hunting expansion.
• Cases are Brass, holding pressure reliably and staying reloadable for handloaders.
• Each box holds 50 rounds, enough for a solid range session.
• A case ships 20 boxes (1000 rounds total), ideal for stocking up or buying once for the season.
• At about $1.45 per round, the price reflects the bullet construction loaded into this round.
• The small hollow point at the tip is a byproduct of the precision swaging process, not a deliberate expansion feature, which is why MatchKings are built and sold for accuracy rather than terminal performance on game.

Frequently Asked Questions

Is the Sierra MatchKing Boat Tail Hollow Point built for hunting or competition? It is a match-grade design built for target accuracy at distance, not for hunting where controlled expansion matters most.

How many rounds come in a case? A case ships 20 boxes of 50, 1000 rounds total.

How is the Sierra MatchKing Boat Tail Hollow Point different from a standard cup-and-core bullet? The hollow point cavity is what starts the expansion process on impact; without it, the same bullet would behave much like a solid, non-expanding round.
