The way you plan to use your firearm is a good guide for which subsonic ammo is best for you. When you're shooting a PCC, Seismic Ammo even makes 185gr rounds with a 950fps muzzle velocity made for suppression on longer barrels and an increased payload on hits.Īs more Americans choose subsonic ammo, manufacturers are increasing their production to provide more good subsonic options. ” The American Eagle 124gr Suppressor 9mm cartridge is excellent for practicing and has a muzzle velocity of 1030 fps. For training and general range use, a favorite is the SIG SAUER 147 GR Elite Ball with a muzzle velocity of 985 and has been lauded by customers as “ great quality ammo. For a subsonic self-defense round, Hornady makes a 147gr JHP XTP with a muzzle velocity of 975 fps. The best 9mm subsonic ammo for pistols and rifles could be manufactured by SIG SAUER and Hornady. Subsonic bullets do not experience transonic destabilization so they have a more predictable trajectory and deliver more energy on target. This may cause you to miss or go off target at extended ranges, as this transition can destabilize the bullet in flight. As the bullet travels, it will lose velocity as the distance traveled increases, and becomes transonic (crossing from supersonic back to subsonic). When shooting at longer ranges, subsonic ammo may be more accurate than supersonic ammo. Competitors also note that subsonic ammo seems to run cleaner in their guns as there is less powder being burned. 95% of the rounds shot at USPSA competitions were subsonic rounds using bullets heavier than 115 grain, with 147 grain making up 47% of the loads. Heavy 9mm subsonic bullets, usually 147 grain, are very common in competition shooting. Subsonic rounds provide you with more benefits, in addition to being quieter, it will reduce recoil and make follow-up shots more accurate. If you eliminate the sonic boom by using subsonic ammo you can significantly reduce sound. Additionally, when you affix a suppressor to your host firearm, suppressors greatly reduce the sound of the gunshot, however, the sonic boom can still be significant. Another benefit of shooting with subsonic 9mm ammo because you’ll reduce recoil, concussion, and sound.
This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases.You can improve your shooting experience with subsonic 9mm ammo because it does not create the sonic boom (aka “sonic crack”) unlike supersonic ammo, which does.
Performance of the Hornady Subsonic load meets or exceeds FBI Protocol terminal ballistic test requirements. They were designed from the beginning to expand reliably at a variety of handgun velocities and deliver deep, terminal penetration with every shot. The XTP bullet is really known for its stopping power. These sections weaken the jacket to allow controlled expansion at low velocities. One of the great things about the XTP bullet is reliable performance, it features controlled expansion where six serrations divide the bullet into six symmetrical sections. Each XTP Bullet has a swaged core and drawn copper jacket to ensure uniform expansion and in-flight stability. Hornady Subsonic Ammunition is designed for accuracy and performance below the speed of sound.
