Question: is 300 blackout the same as 308?
Answer: 308 rounds are leaps and bounds above the 300 BLK rounds with over 1,000ft.lb more energy than the highest 300 round and this trend continues from the muzzle out to 500 yards. You will also notice that the 300 BLK supersonic rounds have a much higher muzzle energy than the subsonic rounds, which makes sense.
