.300BLK is superior. Except...it’s not ubiquitous.
Were I starting out with what I know now, I’d go .300BLK ... but I’m not, I’m pretty deeply vested in 5.56, and the benefits of switching aren’t worth the cost.
Even were I to go all-in with .300BLK, I’d still keep at least one 5.56 rifle on hand precisely because it’s easy to feed from the existing supply chain. With .300BLK, I’d seriously consider buying a pallet ($$$) because I’m not confident in crisis & long-term availability.
I love my AR10, 7.62x51 (.308 Winchester).
Ammo’s easily available, not expensive, AND it hits a ton.
.308 AR10...(or M1A1 or .30-06 Garand)
why play with toys?
Energy on the 5.56 and .300 blk rounds are virtually equal.
.300 blackout is much more energetic than the .30 carbine.
With a 110 grain bullet, velocity on the .30 carbine is 1950 fps. With the .300 blackout, the velocity is 2350 fps.
That means the energy level of the .300 blackout is 45% greater than the energy of the carbine.
The .300 blk approaches .30-30 levels.
Great article, but they really need to check the grammar.
I’ll stick with my 300 Winchester magnum for hogs, thank you.
Absolute, serious hogwash. The 300BO's major claim to fame is subsonic, heavy bullet, suppressed. That is it. It retains the same case as the 5.56, so can only generate roughly equivelant energies.
The 6.5 Grendel, on the other hand, utilizes a larger case and a much more ballistically superior projectile to achieve higher energies at ALL ranges, and can remain supersonic out past 1000 yards, and still within the AR-15 platform.
Knowing a little about the platform, I would recommend to anyone interested in achieving the most possible out of thier AR-15, to do some research on the 6.5 Grendel varient. Once you know the facts, the choice is clear.
A 200 gr bullet from the 300 blk has a vel of ~ 1000 fps, roughly the same as a 45 ACP, but in a much larger heavier platform. What’s the point except it is good with silencers?
