1000 Rounds of 9mm Subsonic Ammo by Magtech - 147gr FMJ FN

Out of Stock

Ammo Overview

Ammo Quantity - 1,000 rounds per case; 50 rounds per box
Ammo Manufacturer - Magtech
Projectiles - 147 grain full metal jacket flat nose (FMJ FN)
Ammo Casings - Boxer-primed brass


Looking for a good 9mm cartridge to chamber in your suppressed pistol? Then look no further -- Magtech’s subsonic load only has a 990 fps muzzle velocity, so it doesn’t produce a supersonic crack that creates more work for a suppressor to muffle. It furthermore combines the quality and affordability that any serious shooting enthusiast likes to see.

This round accomplishes its slow speed with its big bullet, which weighs 147 grains. It’s a flat nose projectile, which target shooters favor for its ability to cut cleaner holes through paper. That helps to leave any guesswork out of scoring. Magtech’s full metal jacket will help you stay on target by averting the kind of barrel leading that gradually depletes accuracy.

These 1,000 rounds’ brass casings will give any handloader lots of opportunities to make their own subsonic loads back at home. Non-corrosive primers take any worry that you can’t get to so many rounds in a timely fashion out of the picture!

A: Most 9mm handgun ammo is traveling just over the speed of sound. This is good from a ballistic standpoint - the faster the better, in most cases - but bad if the ammo is to be used with a silencer/sound suppressor, because the "crack" of the bullet going through the sound barrier will make a lot of noise even if the sound of the weapon firing is muted.

Subsonic ammo uses a heavier, slower bullet that will not break the sound barrier. It will still travel very far, but will drop more at longer ranges (say, 100 or 200 yards). This is not an issue for most people, but if you are shooting that far, you can simply correct for the greater bullet drop by aiming slightly higher.

Another consideration is practice for the use of defensive ammo - if you carry or use 147gr 9mm ammo for home defense, you might want to use 147gr ammo for practice and training use.
