# .338 Thunder #### Overview --- The **.338 Thunder** is a rifle cartridge based on the .308 Winchester case necked up to take .338 caliber projectiles. It was created by AMJ Precision in 2022 and intended as a special purpose big bore cartridge with reasonable recoil for lightweight self loading rifles. Unlike most necked up calibers of its kind it only sacrifices a single round of capacity in a standard 20 round magazine, providing 19 rounds of .338 Caliber ammunition in an AR-10 Platform. #### Stats --- Note: 343.2 m/s is the subsonic barrier - anything below that is considered subsonic. Subsonic ammunition removes the bullet crack down range making the round better suited to stealth.
