Description
CCI Blazer Suppressor 9mm 147gr TMJ ammunition combines CCI’s reliable priming with reloadable brass cases and clean-burning propellants. Each cartridge carries a 147 grain Total Metal Jacket bullet at a rated 900 feet per second. This Clean-Fire Suppressor load keeps the heavy 147 grain bullet below the speed of sound and pairs it with a lead-free primer, so suppressed pistols and carbines run quieter and stay cleaner.

- 147 grain Total Metal Jacket bullet bullet
- Rated 900 fps
- Boxer-primed, reloadable brass cases
- Clean-burning propellants for less fouling

CCI Blazer Suppressor 9mm 147gr TMJ Features
- Subsonic 900 fps velocity for quiet suppressed shooting

- Lead-free Clean-Fire primer reduces airborne lead
- Less fouling in the barrel and suppressor
- Meets power factor requirements for competition
Most full-size and compact 9mm pistols cycle 147 grain loads reliably, but subsonic rounds make less energy than hotter practice ammunition, so run a few magazines through your own gun before a match or class, especially with a booster-equipped suppressor. In a pistol-caliber carbine, the longer barrel can push some heavy loads close to the sound barrier, so check your setup if absolute quiet is the goal. As 9mm suppressor ammo, this load is also pleasant without a can, with a soft push instead of a sharp snap.
Keep subsonic rounds in clearly marked magazines so they do not get mixed with standard-velocity ammunition, since point of impact can shift with bullet weight. The brass cases are reloadable, so handloaders can collect their empties for future builds.

Why Subsonic 9mm Ammo Makes Sense With a Suppressor
Standard 115 and 124 grain 9mm loads usually leave the barrel faster than sound, and that supersonic crack follows the bullet no matter how good your suppressor is. The heavy 147 grain bullet in this subsonic 9mm ammo stays under that line, so the loudest sound left is often the slide cycling. That makes it a favorite for indoor ranges and suppressed pistol-caliber carbines.
Suppressors collect carbon and lead with every shot. The Total Metal Jacket bullet encloses the lead core and the lead-free primer keeps heavy metals out of the blast, so the can and barrel stay cleaner over long sessions.
The 147 grain weight also delivers a soft, pushing recoil that many shooters prefer, and it still makes power factor for several competition divisions, so one box can serve for training and matches.
CCI has built ammunition and primers in Lewiston, Idaho since the 1950s, and Blazer Brass is one of the most popular range loads in the country. The reloadable brass cases are a bonus for handloaders, who can collect and reuse their brass after each range trip.
Suppressor owners, pistol-caliber carbine shooters and competitors who want a quiet, clean-running 9mm load will get dependable service from this 50-round box. Always confirm your firearm is chambered for 9mm Luger, wear eye and ear protection, and follow all federal, state and local laws.
Shooters choose blazer brass ammo because it balances cost and quality. You get the same reliable CCI primers and consistent powder charges found in more expensive loads, with brass cases you can reload, at a price that makes regular practice realistic. For many shooters it is the default box they reach for whenever they head to the range.
Store this ammunition in a cool, dry place in its original packaging so the lot number stays with it. If you shoot often, buying several boxes of the same lot keeps your point of impact consistent from session to session.
