The ultimate competition/match shooting round and the quietest subsonic pistol round out there. These will cycle suppressed or un-suppressed for pistols and un-suppressed in all platforms for a super light recoil. Subsonic loads for 9mm commonly use 9.5 grams (147 gr) bullets at. This provides a balance between speed and supersonic qualities since it is flirting with the supersonic sound barrier of 1,125 feet per second. Subsonic ammunition is ammunition designed to operate at velocities below the speed of sound. 20 Jacketed Hollow Point Center Fire Pistol Cartridges, 9MM Luger, 147GR, ELITE V-CROWN - Optimized jacketed hollow point centerfire ammunition for superior. These heavyweights were delightful to shoot, so if you’re looking for soft-shooting, hard-hitting bullets, give them a try. Subsonic 9mm loads from Bullets 1st use 147-grain projectiles traveling at 1,020 feet per second. So, if you are like some folks who prefer the recoil impulse of heavy bullets because it feels more like a push compared to the snap of light weight bullets. Rounds generally must achieve a power factor of 120 or 125 to qualify for Minor power factor scoring, depending on the sport (IPSC, USPSA, IDPA, Bianchi Cup), and heavy bullets are said to be more effective at knocking down steel plates even when they are at the same power factor as lighter bullets. Most rifle loadings are all supersonic, so subsonic loads are specially down-loaded to stay below the speed of sound. In 9mm, most loading data are supersonic. Another advantage to heavy bullets is their reported enhanced reliability in taking down steel targets used in various practical competitions. All data in this caliber is subsonic but is not normally tagged with the name subsonic. Heavy bullets in 9mm are not just for suppressed guns. Thousands of police agencies adopted the 9mm subsonic as a duty load based on lab tests performed by a single agency, the same agency that claimed to have identified the stopping-power problem. That said, 147-grain bullets, which travel around 1000 to 1050 fps from the typical pistol barrel, are not bound to break the sound barrier, either, though some might at some temperatures and from long barrels. Abstract When the 9mm, 147 grain subsonic hollowpoint was introduced in September 1987, it was hailed as the solution to a tough stopping-power problem. Long grooves in its gilding metal jacket combine with the bullets flat profile and the patented Flex Tip insert within its hollowpoint cavity to help it expand. In fact, most 9mm ammunition with 165-grain and heavier bullets are use for this purpose. Must be shipped to an FFL or Licensed Ammunition Vendor unless you are an exempt peace officer. That makes them a good choice for suppressed guns as they will remain subsonic and won’t produce the “crack” sound of little sonic booms that faster bullets do when they break the sound barrier. Ruag 9mm Ammunition 270640050 147 Grain Subsonic Hollow Point 50 Rounds. Advertised speeds for our 165-grain bullet are around 880 fps or less from pistols and are not likely to reach the speed of sound even from the longer barrels of submachine guns and carbines. Why such a heavy bullet? What do 165-grain bullets do that a 115-grain bullet can’t? The heavy bullets are slower and won’t break the sound barrier, which is 1125 feet per second at 68˚F.
