    Well I see you are back to asking questions that make little sense. Why don't you take the time to read about the 300 BLK and understand it.

    I can probably hit something with 9mm bullet at 200 yards. It doesn't mean it makes sense.

    5.56 vs. 300BLK

    What are your intentions? Hunting rifle, plinking or just a general use rifle? In a 16" rifle there will be a difference but under 300 yards ( I'm too dumb to metric) I don't think you'll see a huge difference in target shooting. As to the differences in energy delivered at 100, 200, 300 yards there are ballistics posts that are a wealth of information.

    I think it boils down to what you intend to do with it.

    0-200 yards, cost and logistics aside, I can't think of why you would choose 5.56 over 300 blk. Much past that, and intermediate ballistics will determine your choice, as terminally both are competent beyond your distance of competency, imo

    Can the ban hammer please be swung more on some of the stupidity that is coming to this forum?


    I've hit steel at 200 with a 9mm just to try it. It sounds like a rock being thrown at a coffee can and has about the same effect.....

    It's equivalent to a hit from M193 at 600 yards from a 14.5" M4 carbine. I still wouldn't want to receive it!

    I've done some shooting at 160 with my G19 and while fun, and certainly potentially lethal, it was a total game of chance at my skill level.

    Seriously though, everyone has to start somewhere on the knowledge tree. I ask stupid questions at times, I think we all do, when we step outside of our comfort zones and venture into territory that is new to us. Is OP TRYING to be stupid, or is OP just ignorant, I guess is my question.

    The 300 is a great cartridge but its not a long range round. It drops like a rock.

    With good ammo a 5.56 RECCE is nipping at 1000 yards. My DMR with its 20 inch barrel and M262 was a solid 600 yard gun. Only reason I say it was that short was the 4x ACOG being the limiting factor. Ive shot trucks with it out past 800 yards.

    No dude is going to get shot in the chest at 300 yards and look down and say "What is that, a 3 MOA group?"

    We were taking my 16" and a 14.5" out to 750 a couple weeks ago in Eastern Washington. The guns can easily do it.

    It was actually quite interesting for me as it all but eliminated my desire to have a 300blk. For all it's "stopping power" arguments, it's just not as versatile as 556. I mean, it would be cool to shoot expensive 220gr subs quietly, but it wouldn't be as quite as a bolt gun, and if it wanted to kill something it would be with supers anyhow. It's in the back of my mind, but considering a 14.5"-16" carbine is quite manageable and with a pre-zeroed scope can be taken to 600+ effectively... I just can't see supporting another caliber right now. ESP not one that can be chambered in my 556 guns with disastrous consequences.

    If I thought the smallest/shortest carbine was desirable than 300blk is cool, but after comparing an 8" 300 to my 12.5 to and then to other 14.5 and 16" guns, it's a pretty minor difference all around.

    Anyone else feel the same? What if we were comparing a 5.56 RECCE with an identical 6.8 SPC rifle optimized for the round, like the LWRC Six8 but without the piston? If it had a dedicated magazine, well, bolt, etc, what would be the disadvantage to shooting a bigger intermediate cartridge?

    If my OP came across as ignorant, I apologize. I know .300 vs 5.56 has been rehashed for close to a decade, but I wanted a fresh opinion. If it was just too stupid for you to handle, there's a handy backwards arrow at the top-left-corner of your screen that you might find useful. For those of you who were kind enough to give your thoughts in a positive light, I appreciate it.

    Nope.

    If you need to support a dedicated mag, bolt, barrel, basically an entire gun you're looking at something different than 300blk vs 556.

    If you feel you can support an entirely differently platform, go for it. 6.8 makes for some interesting crossover. However... imo 6.5G does everything but short barrels better.... BUT, why stop there!? Let's design a 6.7mm wildcat!!! And so on and so on... Pretty soon, you might wonder why you ****ing suck compared to the guy that got 4x more trigger time on his 556 for all the work and effort you put into your gun.

    If your hobby is shooting... 556. If your hobby is reloading or tinkering, 6.8mm. If your hobby is hunting 6.5mm. If you absolutely must have extra lethality or short barrel work within 200y, 300blk. If you even have to ask the questions asked above.... 556.
