Frequently Asked Questions
Buy 223 WSSM Ammo for Sale
What is the drop at 300 yards for 223 WSSM?
For a 55-grain .223 WSSM load at 3,850 fps with a 100-yard zero, bullet drop at 300 yards is approximately 4.4 inches. Drop varies with bullet weight and velocity, so check your specific load's ballistics data for precision.
What is the difference between 223 and 223 WSSM?
.223 WSSM fires faster—3,850 fps versus 3,240 fps for .223 Remington—delivering flatter trajectory and more energy. Trade-offs: WSSM uses more powder, generates higher recoil, costs more, wears barrels faster, and has limited rifle and ammo availability. .223 Rem offers broader options and lower expense.
What is the barrel life of a 223 WSSM?
Barrel life for the .223 WSSM varies widely by load and maintenance. The 1,000–1,500 round figure represents a worst-case scenario. Chrome-lined factory barrels can last considerably longer. Heavier bullets at moderate loads extend barrel life, while light 50–55gr bullets at maximum velocity with poor maintenance accelerates throat erosion.
What's better, 55gr or 62gr?
Neither is universally better—it depends on your barrel's twist rate and intended use. 55-grain shoots flatter and faster; 62-grain penetrates better and stabilizes well in 1:7 or 1:8 twist barrels. Match your ammo to your twist rate for best accuracy.
