The maximum effective range of a 338 ARC rifle is typically 400 yards for supersonic ammunition and 200 yards for subsonic ammunition. The exact range depends heavily on whether you are prioritizing terminal bullet expansion, target shooting, or acoustic stealth.

The data above is based on a 16-inch barrel with a 100-yard zero. The supersonic data utilizes the Hornady 175-grain HP Match BLACK load (2,075 fps muzzle velocity). The subsonic data utilizes the heavy Hornady 307-grain Sub-X load (1,050 fps muzzle velocity).
Supersonic Effective Range
When firing lighter 175-grain projectiles, the 338 ARC is a highly capable medium range cartridge. Out to 400 yards, the bullet retains roughly 1,400 fps, which is generally the minimum velocity required for standard expanding rifle bullets to open up upon impact. Past 400 yards, the bullet drop accelerates aggressively and velocity falls below the expansion threshold, limiting its practical effectiveness.
Subsonic Effective Range
The 338 ARC was designed to excel as a heavy hitting subsonic cartridge. By launching a massive 307-grain bullet exactly at the speed of sound, it delivers devastating close quarters energy while remaining incredibly quiet when suppressed. However, gravity takes an immediate toll. At 200 yards, the bullet drops over 32 inches. Pushing past 200 yards becomes wildly impractical due to a mortar like trajectory that drops over 8 feet at 300 yards.
338 ARC Hunting Range
For ethical hunting on medium game like whitetail deer or feral hogs, your range is dictated by kinetic energy and bullet expansion. With supersonic loads, the practical hunting range is roughly 300 to 400 yards, as the bullet reliably retains over 750 ft-lbs of energy. With subsonic expanding loads like the Hornady Sub-X, the hunting range should be strictly limited to 150 yards to ensure proper penetration and an ethical harvest.
338 ARC vs. 300 Blackout
Both cartridges are designed for optimal AR-15 subsonic performance, but the 338 ARC hits significantly harder. While a subsonic 300 Blackout typically fires a 220-grain bullet producing around 500 ft-lbs of muzzle energy, the 338 ARC pushes a massive 307-grain bullet producing over 750 ft-lbs of energy. The 338 ARC delivers 50% more kinetic energy at identical subsonic speeds, making it far superior for short range energy transfer.
FAQs
What is the max effective range of 338 ARC?
The maximum effective range is 400 yards for supersonic ammunition and 150 to 200 yards for subsonic ammunition.
Is 338 ARC good for long range?
No. The 338 ARC is specifically designed for short to medium range engagements and maximum energy transfer. It lacks the velocity and aerodynamic profile required for long range precision shooting past 500 yards.
How much does 338 ARC drop at 300 yards?
With a 100-yard zero, a supersonic 175-grain bullet will drop approximately 22 inches at 300 yards. A subsonic 307-grain bullet will drop roughly 101 inches at 300 yards.
What is the effective hunting range of 338 ARC?
You can ethically hunt medium game out to 300 or 400 yards with supersonic expanding ammunition. Subsonic hunting should be kept inside 150 yards using specialized expanding bullets.
Does barrel length affect 338 ARC effective range?
Yes, but mostly for supersonic loads. Cutting the barrel from 16 inches down to 8 inches will reduce your supersonic effective range by about 100 yards. Barrel length has almost no effect on subsonic range, as the rounds are already capped below 1,050 fps.
