.375 Raptor 400 gr. Subsonic Maker REX (New packaged 50 rnds./box)


These 400 gr. .375 Raptor subsonic cartridges feature the REX projectile made by Maker Bullets. Their attention to science and precision is unmatched and it definitely shows in the ballistics. They perform best in firearms with barrels that are 16" or less. The casings are formed from new, never fired 7.62 NATO or .308 Win. casings. If 7.62 NATO casings are used these cartridges will show annealing marks and may have traces of cartridge sealant.

The projectiles are CNC machined lead free copper and engineered to perform flawlessly upon impact with flesh. Their design results in extreme trauma from devastating temporary and permanent cavitation making them top choice for subsonic hunting and defense by professionals all over.

These cartridges have been tested and confirmed to function reliably in gas operated firearms with a carbine length gas system featuring an oversize gas port and adjustable gas block.

This cartridge is a "wildcat cartridge" and as such it will NOT be designated with the proper headstamp. Because of this the terms of sale for this product are that TNT Munitions will NOT be responsible for any misuse of this product such as discharging in the wrongly chambered firearm.

To be sure of proper bullet stabilzation and prevent accidental suppressor damage we recommend to first discharge a few rounds at a clean target without a suppressor attached. Then observe target for signs of keyholing. If none is present then discharge with suppressor attached. If this subsonic ammunition will be discharged in a gas operated firearm it is recommended that such firearm incorporates the shortest length gas system possible or at the least an oversized gas port with an adjustable gas block installed to ensure proper functioning.

"Groups well @ 100yrds when sighted. Shoots about 2” below the 190 grain at 100yrds. Nice to know I’m still in the kill zone without changing my zero. I haven’t shot it suppressed yet."
