S&B .223 Rem HPBT/OTM is a cartridge with a 4.5-gram (69-grain) precision bullet for sport and competition shooting. The HPBT bullet’s small frontal cavity, tapered rear, and ballistic coefficient G1 0.340 support stable flight and consistent accuracy. The manufacturer’s published muzzle velocity is 920 m/s and muzzle energy 1904 J. Suitable for use with Rifles precisely chambered for .223 Remington Sport and competition shooting Precision shooting Training at medium and longer range distances Testing the grouping of the weapon and ammunition batch Shooters who prefer a 69-grain HPBT/OTM bullet Firearms with a twist rate specified by the manufacturer as 1:7" to 1:10" Shooters who want a heavier .223 Rem load than the standard 55-grain bullet Why choose S&B .223 Rem HPBT/OTM? HPBT bullet designed for precision shooting Bullet weight of 4.5 g or 69 gr Small technological cavity at the bullet tip Aerodynamic Boat Tail (tapered rear) Manufacturer-stated excellent accuracy and consistency Ballistic coefficient G1 0.340 Ballistic coefficient G7 0.169 Muzzle velocity 920 m/s Muzzle energy 1904 J Manufacturer-specified twist rate 1:7"–1:10" Standard pressure load, not +P 20 cartridges per box Technical data Caliber: .223 Remington Bullet type: HPBT / OTM HPBT meaning: Hollow Point Boat Tail OTM meaning: Open Tip Match Intended use: sport and precision shooting Bullet weight: 4.50 g / 69 gr Bullet construction: precision bullet with open tip and tapered rear Bullet effect: not intended as a controlled-expansion hunting bullet Jacket material: CuZn 10 Bullet number: 2887 Sectional density: 0.196 lb/in² Ballistic coefficient: G1 0.340 Ballistic coefficient: G7 0.169 Manufacturer-specified twist rate: 1:7"–1:10" Maximum point-blank range MRD: 184 m Total cartridge weight: 13.1 g Cartridge length: 57.00 mm Case material: not specified on the manufacturer’s official page +P load: no Estimated power factor: 208.2 kgr·fps Test barrel length: 510 mm Ballistic data At muzzle: 920 m/s and 1904 J At 100 m: 826 m/s and 1535 J At 200 m: 737 m/s and 1223 J At 300 m: 654 m/s and 962 J At 400 m: 577 m/s and 748 J The manufacturer’s ballistic values are measured with a 510 mm test barrel. Actual velocity and energy may vary depending on barrel length and twist rate, firearm design, ammunition batch, and environmental conditions. Trajectory comparison data Manufacturer’s published points of impact with sights zeroed at 100 meters: 50 m: –0.9 cm 100 m: 0.0 cm 200 m: –9.4 cm 300 m: –37.0 cm 400 m: –87.7 cm 500 m: –168.1 cm 600 m: –288 cm 700 m: –459 cm 800 m: –703 cm 900 m: –1039 cm 1000 m: –1483 cm Manufacturer’s MRD comparison data, with maximum point-blank range at 184 m: 50 m: +1.0 cm 100 m: +3.7 cm 200 m: –2.0 cm 300 m: –25.9 cm 400 m: –72.9 cm 500 m: –149.6 cm 600 m: –265 cm 700 m: –433 cm 800 m: –673 cm 900 m: –1006 cm 1000 m: –1446 cm These are the manufacturer’s published reference data. The actual point of impact depends, among other things, on sight height, barrel length, twist rate, temperature, air pressure, and wind. Publishing data up to 1000 meters does not automatically mean the load or firearm is practically suitable at that distance. In the package Cartridges per box: 20 Boxes per shipping case: 50 Cartridges per shipping case: 1000 Approximate box weight: 0.28 kg Approximate shipping case weight: 14.2 kg Frequently Asked Questions What does HPBT mean? HPBT stands for Hollow Point Boat Tail. The bullet tip has a small cavity, and the rear is aerodynamically tapered. This construction is designed primarily to improve accuracy and stable flight. What does OTM mean? OTM means Open Tip Match, i.e., a precision bullet with an open tip. The tip opening results from the manufacturing process and does not mean the bullet is designed to function as a controlled-expansion hunting bullet. Does the HPBT bullet expand like a hunting hollow-point bullet? Controlled expansion is not the main purpose of this bullet. S&B classifies the load in the Target/Match category and recommends it for sport shooting. For hunting, choose a hunting bullet with the appropriate performance and construction for local regulations. What twist rate is suitable for this 69-grain bullet? Sellier & Bellot specifies a suitable range of 1:7" to 1:10". The actual stabilization and accuracy depend on the specific barrel, its length, condition, and shooting conditions. How does the 69-grain HPBT differ from the standard 55-grain FMJ bullet? The 69-grain bullet is heavier and has a G1 ballistic coefficient of 0.340. This provides better retention of velocity and less wind drift, but the real advantage depends on shooting distance, barrel, and weather. The 55-grain FMJ is usually a more economical choice for regular short-range training. Can the cartridge be used in a semi-automatic .223 Rem firearm? The cartridge overall length is 57.00 mm, but suitability should be confirmed by the firearm’s manual, chamber marking, and magazine. Before buying a larger quantity, check feeding, locking, case ejection, and grouping in your firearm. Can a .223 Rem cartridge be used in a 5.56×45 NATO firearm? Use the cartridge only in firearms whose manufacturer allows the use of .223 Remington ammunition. Although many 5.56×45 NATO chambers accept .223 Rem cartridges, compatibility must always be confirmed by the firearm’s markings and manual. Do the 1000-meter trajectory data mean the cartridge is suitable for 1000-meter competitions? No. The table shows the calculated trajectory, not a guaranteed practical range. Suitability depends on the firearm, barrel twist, sights, shooter’s skills, and environmental conditions. When is S&B .223 Rem HPBT/OTM the right choice? This load is suitable for sport shooters who want a heavier, higher ballistic coefficient precision bullet than the standard 55-grain .223 Rem cartridge. The 69-grain HPBT combines a muzzle velocity of 920 m/s, G1 ballistic coefficient 0.340, and a construction designed for Target/Match use. For regular short-range training, a more affordable FMJ cartridge may be more practical. A lighter 52-grain HPBT may suit a firearm with a different twist rate or shooting distance. For hunting, choose an SP or other suitable hunting bullet designed for that purpose. Expert recommendation With a 69-grain bullet, barrel twist rate is especially important. The manufacturer specifies a range of 1:7"–1:10", but even barrels with the same twist can produce different groupings. Before competitions, test at least several boxes from the same batch and check results at actual match distances. If switching from a 55-grain FMJ load to a 69-grain HPBT cartridge, recheck your sight settings. Record temperature, wind, and point of impact at different distances, and create a ballistic profile for your firearm based on actual measurements. Always use hearing and eye protection when shooting. 69-grain .223 Rem precision cartridge for sport shooting S&B .223 Rem HPBT/OTM 4.5 g combines a heavy precision bullet, aerodynamic Boat Tail rear, and ballistics suitable for sport shooting.
