It will not out shoot the .308 in anyway whatsoever and its nowhere near as powerful but it has similar ballistics from 0 to 600 yards as a .308 has from 250 to 800 yards using a compatible bullet weight loaded in commercial self defense/ hunting ammunition.
Thats the most idiotic biased comparison I have ever read in my life.
You are basing a light bullet load in the 308 to make the 300 blk look better by comparison.
Okay here you go - real world - if you want to talk about long distance shooting - this vs that.
Use these loads -
300 blk best hottest long distance load you can find vs 308 best long distance load.
Both 20" bbls
Just to be friendly we will look at a 125 pill out of a 300 blk at 2325 - 1000 FPE at 200 yards.
My old 308 with a 20" bbl will spit out a 208 gr amax at 2500 fps over RL17 - 1000 FPE at 900 yards.
So the correct comparison should be whatever you can kill with a 308 at 900 yards matches the 300 blk at 200 yards.
The 300 blk is a decent weapon within its limitations and from Subs to super with no changes is nice, but in the end its nothing special.
Just basically 30-30 Ballistics that you can shoot sub-sonic, so get real, if its not too late.
Insanity: doing the same thing over and over again and expecting different results.
You guys, (whoever you are pushing this BS) will never be able to convince people with the least bit of common sense that the 300 blk is right for every situation.
So far I read its its almost as good as a 308, perfect for hunting at 300 yards (lob em in at 650 FPE), great for Black bear hunting, Cougars, Deer, Hogs.
Pretty soon somebody is bound to start yacking about taking one to AK to hunt Moose or taking one to Africa.
Id never recommend it for hunting bear.
Im not talking about Long distance shooting.
Lets use your comparison
a 208gr AMAX with a BC of 0.648 leaving the muzzle of a 20" barrel at 2500fps will be running at 2174 fps and 2182ft lbs of energy at 250 yards and at 900 yards will be around 1457fps and 980 ft lbs.
a Corbon 125gr Nosler BT from a .300 Blackout 16" barrel (20" barrel negates the benefits of having a lighter smaller rifle.) starts out at 2250fps and around 200 yards is 1923 fps and 962ft lbs and at 400 yards is 1458fps and 590ft lbs
What Ive been saying this whole time is that the .308 winchester is effective out to 1000+ yards, It is undoubtedly More Powerful than a .300 Blackout, the .300 blackout does not come anywhere near what the .308 is capable of in terms of Range, and in terms of short range power, But what i am saying is that for a short distance after 250 yards the .308 and at the muzzle for .300blk that they share similar velocity and Energy for a few hundred yards.
2250 fps and 1405ft lbs through 1458fps and 590ft lbs is still Lethal, It WILL NOT have the range of the .308, But in these shorter distances it is still powerful enough, but with the advantages of Less Muzzle Blast (.308 out of a 16 inch barrel is a fireball) a Lighter weapon platform (AR-10 vs AR-15). You will also not have great success with a .308 from a 10 inch or even shorter barrel.
YES the .308 handles heavier bullets and Blows away the .300 blackout once they get past 155gr bullets.
NO the .300blk isnt the end all be all, but it does provide a light weight platform with more energy than a standard 5.56.
So In my Opinion:
The .300 Blackout is a better choice for 0-600 yards.
The .308 is a better choice from 0-1000+ yards
But the .308 will be heavier, and if you dont need the extra range then why not go for the .300 blackout instead?
