Is the 300 blackout really all that??

So I'm looking to build my own upper for my wife (she saw a pic of one with pink furniture and wants one) so I figured I'd put one together for her and want something different. Thinking a 300BO might be fun but it seems to me it would be too much bullet and not enough powder?? Just speculations on my part. Can someone fill me in on ballistics compared to a .556?
 
I think for the general market there is no point for a 300 blckout..JMO. Stick with 223/556 or if you want bigger, step up to the 7.62 or 6.8 or 6.5x55 uppers.

Short range for what? thats the question. Short range for javelina sized game??? not even worth it
 
It's a 30-30 in an AR. Plenty for deer at typical 30-30 ranges. And a short barrel with a can is awesome. Great hog gun in my opinion.

Of course, some folks think if they couldn't use it, no one else should either...
 
In short yes it is all that. Uses standard mags and bolt. Easy to load for. Shoots well both subsonic and sonic. Can be used with barrel length from 8.5-16 with an 8 twist, and has really good accuracy potential. Recoil is nada. Prior to the ar scare of '13 ammo was off the shelf available.
I have taken yotes, deer, chucks, and other sundry critters with out fail.
I am sold on the round. With that being said, it is not my only ar platform. It is not my go to longer range round. It is my stupid quiet close up round.
 
In my opinion, if you're not going to SBR and run a can on a 300blk rifle, it's not worth it. If you want a longer barrel and a different round, look at a 6.8spc, 264lbc or 6.5 grendel. The problem I had with those cartridges is the extra cost and availability of brass, bolts and magazines.

I have the Eotech XPS 2-2 on my 10.5" upper and it works great for 110gr supers and 220gr subs. If I zero the 110's at 100 yds with the top dot my 220's are about 1/2" low at 100 yds on the second dot. I can reliably hit a 4" steel plate at 300yds with the 110's using the second dot and the 220's are at about the bottom of the hash mark at the bottom of the reticle. Once I figured that out, I was hitting the plate about every other shot with the subs.

I make my own brass, I've even used 5.56 blanks to make 300blk brass. At least you know it's once fired!

The 300 isn't for everybody, but if you want cheap brass, same bolt, same magazines and shoot small game or large varmints inside 200 yds, then this cartridge works fine. If you want a longer range, harder hitting cartridge, that's what they make the 308 for.

Ballistics are closer to a .30 carbine than a 30-30 in my view. I don't own a 300BO; I would probably think it was the cat's meow if I did. I certainly see its niche if you want a suppressed sbr or short carbine on the AR15 platform. That is where it shines and its raison d'etre I reckon. Beyond that ( unsuppressed, standard length) I think you would be much better off with a .556, Grendel, or 68. My .02.

Don't misinterpret me...
If you want it, get it. I just feel there are better options. To each his own.

closer to 30 carbine? really?
not much opinion to be had there, the ballistics are what they are. there are more that a few threads about the ballistics.

i would never attempt to take a deer with a 30 carbine, but a 300bo, sure, with proper shot placement and range 100 yards or under.
 
I think I'll stick to a .556/223 I don't want to limit my shots on deer sized game to 100 yards and I'm already reloading for my other AR. Just figured I would ask since there seemed to be some hype on the round.

Safe thinking!!!! There is no way a person could bring down a whitetale deer with a round (non-pointy) lead tipped (non-plastic)bullet of same weight going 100-200 fps slower; especially "with proper shot placement and range 100 yards or under".
 
6.8 is a great low recoil, hog and deer cal in the AR plateform.

My wife and daughter both used it this passed WT season and took a total of 3 WT....one shot kill, DRT

Check out the 6.8 forum to learn more.

+1, I really enjoy shooting mine super and subsonic.

maybe i am misunderstanding your post, so if i am, i apologize. but it appears that you are claiming that the 300BO is slower than a 30 carbine.

hornady reloading manual, page 606, 30 carbine data. 110gr round nose bullet is listed with a max velocity of 1700fps.

sierra reloading manual, page 918, 300 whisper data. 125gr spitzer listed with max velocity of 2000 fps. OUT OF A 10" BARREL.

i have personally loaded and chronographed 125gr speer bullets out of a 16" barrel 300BO at 2250fps. those were not max loads.

Its a fun cartridge in its own niche. If I were to build a hunting gun for the Mrs or Kids on an AR I would lean to the Grendel or the 6.8.

what he said. However, the Grendel or .264lbc (basically the same thing) outpaces the 6.8 by a large margin once past 300 yards with its high BC pills
