S&B .22 LR Subsonic HP is a rimfire cartridge with a 40-grain (2.60-gram) hollow point lead bullet. The manufacturer-measured velocity at 5 meters is 300 m/s, which means the bullet remains subsonic under normal conditions. This load is especially suitable for practice with controlled sound levels and for use with a suppressor in firearms approved by the manufacturer for .22 LR ammunition. Suitable for use with .22 LR caliber rifles .22 LR caliber pistols Suppressed firearms, where suppressor use is permitted by law Target practice with lower sound signature Target shooting and recreational shooting Shooters who prefer a 40-grain subsonic load Testing firearm and suppressor reliability Legally permitted hunting, if caliber, energy, and bullet construction meet requirements Why choose S&B .22 LR Subsonic HP? Subsonic 40 gr (2.60 g) load Hollow point lead bullet Velocity 300 m/s at 5 meters Energy 117 J at 5 meters Velocity 270 m/s and energy 95 J at 50 meters Ballistic coefficient G1 0.110 Suitable for use with a suppressor Manufacturer-rated reliable operation Economical choice for regular practice 50 cartridges per box Technical data Caliber: .22 Long Rifle / .22 LR Primer type: rimfire Bullet type: HP / LHP Bullet construction: hollow point unjacketed lead bullet Bullet weight: 2.60 g / 40 gr Sectional density: 0.143 lb/in² Ballistic coefficient: G1 0.110 Case: CuZn 30 brass alloy Load class: Subsonic Test barrel length: 700 mm Manufacturer-rated features: reliable and economical Ballistic data At 5 m: 300 m/s and 117 J At 50 m: 270 m/s and 95 J Manufacturer data measured with a 700 mm test barrel. Actual velocity may depend on barrel length, chamber, firearm construction, ammunition batch, temperature, and other environmental factors. Trajectory comparison data The manufacturer does not publish sight adjustment distance or bullet drop table for this load. Point of impact and trajectory must be determined with the firearm, sight height, and specific ammunition batch used. The trajectory of a subsonic cartridge generally drops faster at longer distances than an HV load. If you switch to faster or different bullet construction ammunition, always recheck the point of impact. Packaging Cartridges per box: 50 Boxes per shipping case: 100 Cartridges per shipping case: 5000 Approximate box weight: 0.18 kg Approximate shipping case weight: 18.4 kg Frequently Asked Questions What does Subsonic mean? Subsonic means that the manufacturer-rated bullet velocity is below the speed of sound. This load's velocity is 300 m/s at 5 meters. A subsonic bullet does not create the shockwave typical of supersonic flight under normal conditions. Does a subsonic cartridge make shooting completely silent? No. Shooting still produces powder gases, mechanical noise, and the sound of bullet impact. A suppressor can reduce muzzle blast but does not make a firearm silent. Always use proper hearing protection when shooting, even with a suppressor. Does this cartridge work in a semi-automatic firearm? It depends on the firearm. Subsonic loads may provide less energy to operate the mechanism of a semi-automatic firearm than a faster HV cartridge. Before buying in bulk, check feeding, cycling, and case ejection in your firearm. What do HP and LHP mean? HP stands for Hollow Point bullet. LHP denotes a lead hollow point bullet. This is not a jacketed bullet, and its behavior on impact depends on the target, distance, and remaining velocity. Can this be used in .22 Short or .22 WMR firearms? No. .22 Short, .22 Long Rifle, and .22 Winchester Magnum Rimfire are different cartridges. Use this ammunition only in firearms marked and approved for .22 LR cartridges. Why does the manufacturer list bullet weight as 2.60 g, but Jahipaun's product name says 2.56 g? The current manufacturer data sheet lists the bullet weight as 40 gr, i.e., approximately 2.60 g. Jahipaun's sales name uses 2.56 g. For exact product identification, refer to product code V355252 and EAN code 8590690355259. Is the HP bullet suitable for hunting? Suitability depends on the game and local laws. Before hunting, check that .22 LR caliber, bullet construction, and cartridge energy comply with the requirements for the specific game species. When is S&B .22 LR Subsonic HP the right choice? This load is suitable for shooters who want a 40-grain hollow point .22 LR cartridge for practice with a lower sound signature. The manufacturer-rated velocity of 300 m/s remains subsonic under normal conditions and allows the use of a suppressor without the shockwave typical of supersonic bullets. Round-nose Subsonic LRN may be a better choice for regular target shooting if a hollow point bullet is not needed. S&B Club is aimed at precision training, while HV HP offers higher velocity and energy but typically produces a supersonic shockwave. Expert advice .22 LR firearms may react noticeably differently to various cartridge shapes, velocities, and lubricants. Before purchasing in bulk, test your chosen load in your firearm and check accuracy, feeding, and semi-automatic mechanism reliability. When using a suppressor, ensure that bullets hit the target straight and do not show signs of unstable flight. After changing ammunition, always check the point of impact. Use hearing and eye protection when shooting, and clean the barrel, chamber, and suppressor according to firearm and suppressor manufacturer instructions. Store ammunition in a dry, cool place out of reach of children. Subsonic .22 LR hollow point cartridge S&B .22 LR Subsonic HP V355252 combines a 40-grain hollow point lead bullet, 300 m/s velocity, and an economical 50-round box. It is a practical choice for low sound signature training and for use with a suppressor in a compliant .22 LR firearm.
