Now I will pick a few of them to pursue accuracy. That also adds pressure and diminish case life.Īll those are my uneducated opinions based on what I observed during the load tests I had done in the last few weeks. The cases need to be clean from the lubes of sizing during reloading. Subsonic Handgun utilizes tried-and-true XTP bullets that expand reliably at subsonic velocities. Something that I also noticed (in my gun any way) is that some of the powders create a lot of carbon build up and adds to some pressure spikes.Ħ. Hornady Subsonic XTP 9mm Luger 147gr JHP Handgun Ammo - 25 Rounds - Hornady Subsonic Ammunition - designed for accuracy and performance below the speed of sound - now comes in both rifle and handgun loads. Pistol primers, in the other hand,seem to be more gentle with the case since pressure will be noted more earlier than when using a small rifle primer.ĥ. In some cases, it gives you extra velocity at the price of case life shortening.Ĥ. ![]() Rifle primers add significant amount of pressure to the load in a hurry. Using hot loads diminish the case life down to one or two loadings.ģ. T/C G2 Contender can take lots more pressure than pistols.Ģ. ![]() Stock up today!Ĭlick here for answers to Ammo Buying Frequently Asked Questions, and for more information check out our State of the Ammunition Industry page.Ĭheck out some of our other top ammo for sale - 9 mm ammo, 300 Blackout ammo, 6.5 Grendel ammo, 6.5 Creedmoor ammo, 5.56 ammo & 10mm ammo.In a rather short time, I have developed and tested a number of loads in my T/C G2 Contender and I have learned a great deal. Find a variety of subsonic, standard, and rimfire ammo on OpticsPlanet! We offer major brands, muzzle devices, and free shipping on orders $49 or more. There are standard loads as well like subsonic 22, subsonic 223, and subsonic 9mm. Yet, subsonic ammo isn't limited to specialty cartridges. We stock a variety of calibers from subsonic. With a 125-grain bullet, the result is a muzzle velocity of 2,215 feet-per-second with 1,360 foot-pounds of energy. The advantage of subsonic rounds is noise reduction when paired with a suppressed firearm. 300 BLK pairs a large-caliber bullet with a smaller casing. 30-caliber cartridge was based on the popular 5.56mm NATO, a standard military round, but delivers a similar performance to the larger 7.62mm NATO, also a standard military load. What is Subsonic 9mm Ammunition Subsonic ammo is ammunition that does not break the sound barrier, usually around 1100 feet per second, achieved by utilizing a heavier bullet. ![]() One of the most popular and effective loads is 300 blackout subsonic. Yes, subsonic 9mm ammunition can be effective for self-defense. Bullet Type: XTP (eXtreme Terminal Performance) Hollow Point. Caliber: 9mm Luger (9x19mm Parabellum) 2. Therefore, subsonic loads are designed to strike the right balance of velocity and bullet weight. This subsonic ammunition provides exceptional accuracy and terminal effectiveness, while minimizing noise and reducing recoil for a comfortable shooting experience. To do that, ammo makers design the round to travel at velocities below the speed of sound, which creates another problem altogether. Subsonic bullets reduce sound by eliminating the supersonic crack and muzzle blast. ![]() Subsonic ammo reduces recoil, making it an excellent platform for beginning shooters or those who train and compete regularly. The goal when designing a subsonic round is to reduce the noise of the initial crack caused by expelling gases. Subsonic 9mm ammunition is designed to operate at a speed below the speed of sound, generally between Mach 1 and 343 m/s. The benefit of using subsonic ammo is that it's quieter than standard ammunition and makes suppressed fire even more effective, but going subsonic poses a number of challenges for manufacturers.
