300 AAC Blackout, would you buy it again?

I have been thinking about it but talk myself out of it each time. I will more than likely get another one day though.

The 300 BLK excels at one thing really; a suppressor host. If that is the goal then yes 300 BLK is the ticket. If hunting is the goal or any supersonic use for that matter; then I would recommend looking at the 300 HAM'R . It has a good selection of bullets if reloading and out performs all of the 6.8 calibers available to the AR-15 builder. If not planning on reloading the 300 HAM'R is still a decent choice in terms of ammo offerings although not particularly cheap.

I would avoid the 350 Legend; it just isn't ready for prime time yet. Bullet selection is problematic at best.

EDIT: If you're looking to go supersonic but the 300 HAM'R just doesn't float your boat then I'd recommend looking at either the 277 WLV or the 6.8 SPC. Even the 7.62x39 for cheaper ammo options.

EDIT2: FYI the 300 HAM'R, 277 WLV only require a barrel change to a MIL spec AR-15. The others will require bolts and magazine changes as well.

It really shines as a short barrel suppressor host. It’s fine out of a 16” with supers, but that’s not what the caliber was meant for by any stretch of the imagination.

I would go 30 Herret (TAC 30) before the Hamm'r. The 350 is to new for me but as far as bullets all you would have to do is resize 357/38 bullets to the .356 diameter it is.

Welllllllllllll ..................... sort of. Problem with 350 Legend bullet selection is the lack of rifle bullets for it. You can resize pistol bullets but; they are just not designed for the velocities the Legend is capable of. Also; the SAMMI spec on it is like 355 to 358 (thats a pretty wide spread. Add to that manufacturing tolerances and accuracy is all over the place. I'll wait and see how it settles in; but honestly I don't think it will ever amount to much other than a legal straight wall hunting round in some states.

EDIT: And while I agree the 30 TC is a good round; for the AR I would pick the 300 HAM'R

I have taken two nice white tall with a 10” barrel 300 BO pistol About the same as a 30-30 which I would usually carry. Longest shot about 80 meters. It was built to carry on a tractor. Works well

I would not have another one in an ar, the single shot cva one i have will suppress better and that is the main reason to even fool with a 300 in the first place. I know where a new cva is in the box

If you’ll reload for it,do it. If you’re going to feed it factory rounds pass. If all else fails.......you could always re-barrel it into some other caliber.

I’m no subsonic guy but like the heavies (230gn) out of it at 14/1500fps.....some faster. As far as killing something.......it’ll do ok with the mentioned above at 100/125yrds. Possibly farther,I have never shot anything but steel farther than that tho.

Got one of the ACC Handi Rifles a few years ago in the .300BLK. Loved it so much I bought a PSA AR pistol last year. I plan to get a 16" upper in .300 the next time I catch them on sale. Grandkids love shooting the AR, and grandson took a 130lbs doe with the Handi last year.

Bullets for the 357 max/ mag should work ok as the max gets to almost 2K fps. But to me the 350 legend is good for 100 yard in states that require straight wall.

I know several folks that have great success with it. Definitely like seeing someone post something positive about it.

If you load for it and try more than the popular powders you may find a winner that’ll push what you want out of it. The short case is the killer thing tho. You can only pack so much in there.

I bet Shooters World Socom would do good.

Yes.
As long as have a can to use with it. And like above, only if reload for it. Can convert 223 cases and use .30 cal bullets so components are fairly cheap. Would definitely stick with short barrel/pistol. And as long as you understand its limitations it's a good round.
:2cents:

Just re read your first post. To answer your question- no.
Not in a longer barrel and not without a can or reloading. I'd just get an AR 10.

That’s on a whole different scale! Apples to oranges!
And why not the longer barrel? 200fps not worth it to you? Gotta think outside the box and stop listening to the magazine salesmen.
I’m telling you,if you have the time and fortitude there’s other things the round has to offer.

This round is limited but people tend not think outside the box or popular opinion with it. Everyone thinks a heavy pill has to run slow. It’s not so.

Bad thing is......I think those that say it’s like a 30-30,should revisit that round as well. This cartridge isn’t touching anything I load for mine.

True. But if was wanting it to hunt with and not reload for then there are better and cheaper options out there. It's not a round I'd "plink" with for sure if didn't reload for it. And if not suppressing it then don't need it for "tactical" reasons.
Not doubting you with that. My reason for the round was for suppression. So not loading anything hot. And only loaded my super sonic hunting rounds to the most accurate charge.

In 140-180gn yes sir! Never tried anything else. But I have some 30-30 loads that you can use a 180gn lead bullet to knock 1/4” deep holes in 5/8” steel with at 75yards. Bet money there’s not a 300blk load out that will put preform them.
I’ve got a “few” different 300 loads and I haven’t done it lol

Oh I have no doubt that the blk would not out do them. The 30/30 can best the blk (IMO) load for load.

I may have to get that 30/30 load off of you when I start loading for mine.
