Question 1

What is .300 Blackout supersonic ammo for?

Accepted Answer

Supersonic .300 Blackout (110–125gr at 2,200+ fps) delivers .30-caliber performance from an AR-15 platform. It offers more energy than 5.56 at close to medium range while using the same lower receiver, magazines, and bolt carrier group.

Question 2

How does supersonic .300 BLK compare to 5.56?

Accepted Answer

Supersonic .300 BLK delivers more energy at close range (under 200 yards) with a larger .30-caliber bullet. Beyond 200 yards, 5.56 has better trajectory due to higher velocity. .300 BLK costs roughly 2x more per round than 5.56.

Question 3

How much does supersonic .300 Blackout cost?

Accepted Answer

Supersonic .300 BLK FMJ runs $0.50–0.75/rd for range loads. Hunting and defense loads with expanding bullets run $0.70–1.20/rd. Significantly more expensive than 5.56 ($0.30–0.45/rd) due to lower production volume.
