300 black out

[HICOUNTRY]

Hey guys, any of you familiar with this cartrige? or have feed back about it?  thanks

[wheels]

dads friend has one and  been  working on reloads

[headshot5]

It's a fun cartridge.   Short range 200 yards or so supersonic, and 100 yards or so subsonic.  (That's without dialing for range).   Great for reloading, really quiet and fun, but not really practical as a hunting round.  Mines a bolt action.  Really can't speak to the AR-15's.

Subsonics are crazy quiet with a can.

Bknilvr had a thread very recently about this......lotta good info on there.

Why isn't it practical for hunting?

I heard a story of a buck eating a whole bunch of lead from one multiple times at close range.


The shooter now is pretty adamant that it is NOT a deer cartridge.

I guess it would have been better written, as there are better alternatives for big game hunting.   I mostly use mine for coyotes and have used it on deer and elk and it worked fine, but I feel there are better options...  For supersonics the best bullets to use (my experience) are 125gr Nolser ballistic tips, and Speer 130 flat point.

125's expand well, and 130's will expand mildly and penetrate while holding together.

The subsonics are fun, but have a rainbow trajectory.  The real reason I bought mine was to shoot cast bullets in it for fun (and cheaply).  For that it has been excellent.

Most likely yet another use of non-expanding subsonic bullets for hunting. People don't seem to get this; none of the jacketed .30 cal heavy bullets from mainstream manufacturers expand or do significant damage at subsonic speeds. You need to use a bullet specifically designed for subsonic loads, but most people won't spend the time or $.

I would recommend the 6.8 spc over the 300blk. Its a .270 bullet out of basically a .30 cal case.

[WAnoob]

I've read some articles about it, the military favors it for special forces because it can be subsonic and very quiet but still have the same "knock down" power of a hot .45 acp if I remember right.

You could give us some more info as to why you were thi king 300black out.

I have it my mind to build a ar in 6.5grendal. Near 308 balistics out of a 7.62x39 case. Common brass case and they already make ar15 in 762x39 so a different barrel is all thats needed.

A lot of guys in Indiana are getting AR15 pistols and using a 300 blackout to hunt deer because of the states messed up caliber rules.  They love them, use Lancer Mags.  300 Blackout is heavier and GI and PMag followers will cant causing bolt over base. Use the Sierra 125 lead nose or use Hornady or Barnes 110 grain Ballistic tip (Red or Brown), 19 grains of Accurate 1680, OAL 2.260"

You won't be disappointed. I LOVE my GRENDEL...........

thanks for all the good info guys!  just looking for something quiet, so i dont stir up the neighbor hood during the winter when the coyotes get thick and i start calving season...

[DJ_Mack]

I am in the works of buying a Ruger American ranch in 300blk.  Like the guys said earlier, if you are using it with supersonic loads stick with what was listed above.  If you are going subsonic with a can, check out silencerco's website.  They are running a special on their harvester ammo that is subsonic and meant for hunting.  Also check out gemtech's website they sale sample packs of 5 rounds for 4$.

Grendel is flatter shooting than 308 out past 400yrds.   Fireforming AK brass is less than optimal, case capacity can cause problems when reloading, can be done yes and I looked at doing it but just not worth the hassle...  Just buy Amax 123 factory ammo and reload them, you end up way ahead of the game for brass cost, and the amax ammo is damn fine shooting and not that expensive.

Grendel is a great option, I love mine, but you do not get the subsonic option that 300blk offers.  These are my two favorite rounds currently, but they are very different and fill very different roles..

Quiet you cannot beat 300blk, or even a 9mm are shooting 147grn and a can...  300blk there are many bolt actions, then you are talking the quietest possible.  semi auto action does make some noise with release of gases during action....

[TheHunt]

I have a buddy who runs an AR frame and the blackout.  He has a can on it and it is super quiet. 

His main use if coyote hunting and it is a really sweet rifle.   We can whisper, hunt and shoot with out ear protection.  It is really nice.

Only if you're comparing it to FMJ or blunt hunting bullets in the 308. If you compare A-Max or Ballistic Tip bullets in both, the 308 still shoots a little flatter, although they are pretty close in trajectory.

  300 Blackout is heavier and GI and PMag followers will cant causing bolt over base. Use the Sierra 125 lead nose or use Hornady or Barnes 110 grain Ballistic tip (Red or Brown), 19 grains of Accurate 1680, OAL 2.260"

Cant is caused by thickness of the bullets where they contact the magazine ribs, not the bullet weight. It's mostly an issue with subsonics, and a lot of cast bullet profiles. Using the correct bullet for supersonic loads, there's no issue.

There is no red or brown Barnes "Ballistic Tip". There is the Barnes 110gr "Black Tip", which is designed specifically for the 300 Blk, and is different than the blue tipped Barnes TTSX. This Black Tip bullet is arguably the best for supersonic loads in this cartridge. The 125gr Nosler Ballistic Tip also performs very well in this one on game. The 125gr Speer TNT and 125gr Sierra Pro-Hunter can work, but are not as good as the Barnes or Nosler.

My brother built a 300blk ar15 for my daughter to use this year to hunt deer with. We were looking for something that me,my wife or my daughter can shoot size wise and something with little to no recoil for my daughter. This fit the bill very well for my daughter and she was far more comfortable and confident with it than with her 20ga. Zeroed to 100yds and she was set. Unfortunately we never got the chance on a deer with it since most or time was spent in the battleground unit with firearm restriction. She ended up taking a deer with her 20ga. My daughter is 9yrs old and 55lbs and recoil was her biggest issue, 2nd was the fact that she's so small. The adjustable stock, buffer options and recoil are why we went with it. And the fact that my brother had everything laying around to build it already and I didn't have to buy a whole new gun!

The red tip for Hornady; I think when the guy told be Barnes he actually meant Nosler for the brown tip (IDK).  I always like using hornady so that's about all I am familiar with.  I do know he had started out with Sierra and switched.  All of the mag problems we have had has been with supersonic loads and when we switched to Lancer mags they went away.

[Thefisherman83]

My dad killed a deer with mine this year. 110gr Barnes to the boiler room and it fell over dead within 10 yards. It was a 50yd shot.

30 cal Noslers have green tips.

Pmags shouldn't give you any problems with supersonic loads unless you're seating the bullets out to far. 2.060-2.100" OAL is pretty standard for 110-125gr supersonic loads (except for the 110gr Black Tip and 125gr SMK), seating them to 2.260" will definitely cause issues because the ogive is ahead of the magazine ribs.

Dont buy into the acc hype, 300 blackout is a turd!

[carpsniperg2]

Dont buy into the acc hype, 300 blackout is a turd!

It does what it was designed to do. It wasn't designed to be the next 300 RUM

It can be a fine deer rifle with limited range and the correct bullets. I have seen the 125g ballistic tip put deer down in a hurry. A good expanding bullet is the key. Like said for being quiet the 300blk is the perfect choice.

Plenty of people say that about the 30/30 and 35 Remington too, but they do what they're supposed to and put down deer by the truckload.

You just hurt JD Jones' feelings!

The Blackout is a neat caliber if you understand it's limitations. As a hunting cartridge I think it's fine inside of 150 yards. The Blackout in a rifle duplicates what the 30 Herrett does from a 10" Contender. The 30 Herrett is a pretty effective critter killer when loaded with the 125-130gr bullets so I would imagine that the Blackout is just as effective.

agreed👆
Doing what it is designed for, and especially with subsonic specific projectile such as Lehigh makes, a quite amazing round!
Not sure why so many are adding the 6.5 Gren to the discussion. 2 totally different rounds for 2 different purposes. Beside, not what OP was asking about..

[Buzz2401]

Sounds like a good round for bow like ranges.  Doesn't have much energy even at the muzzle and with the low speeds it gonna need a bullet that performs well at under 2000fps.  Sounds like a good brush gun.  I like the idea of using it as a pistol in firearm restriction areas.  Seems like it would really shine there.  I wouldn't really compare this round to the 30-30 though because it has more velocity and energy then a 300blackout

[Biggerhammer]

30 American is a dog! The .300 blackout is steps behind. Subsonic is worthless other than play time and applications the majority on this bored will ever need.

  if the 30 remington was marketed as well as AAC has marketed the blackout, we'd all be singing a different tune. It's a shame cause the 30 rem is a dang fine AR cartridge.

Help me out. Why is that considered a pistol? Can you have a pistol with a shoulder stock?

Sure.... You can shoot empty beer cans in your living room with a good bullet trap and skip the hearing protection. Been there done that!
