How accurate is the 6.8 SPC?
The 6.8 SPC is capable of excellent accuracy as well.

Can 6.8 SPC use 5.56 magazines?

Is Hornady’s SPC ammo good for hog hunting?
An old trick by Hornady, the projectile’s polymer tip guarantees it mushrooms even at decreased velocities. Range-wise, like most 6.8 SPC ammo, 300-yards in is optimal—plenty enough for most dedicated hog hunters. Certainly, the 6.8 SPC doesn’t reach out like a .22-250 Remington or .204 Ruger.
What is the ballistic coefficient of the SST bullet?
The SST (Super Shock Tip) bullet does boast a respectable ballistic coefficient—.400—and the ammo has decent muzzle velocity for the bullet weight—2,460 fps. Still, at 400 yards, the projectile falls in excess of 30 inches, which isn’t the easiest to control for. Get the round on target and you can expect excellent results, however.
