300 blackout

[hso]

AAC recommends 9" for subsonic loads. Some suppressor companies recommend 10-12". No one that I'm familiar with recommends 16".

Black Rain makes very nice rifles, but you pay for that. Can you post a pic and give us an idea what it cost?

The 300 BO is a great cartridge for what it is.
It's a solid performer on white tail size critters.
I took a nice 8 point this year and he just folded up, DRT.
If you reload it can be down right dirt cheap to shoot also.
It's no 308 or 708 but it's definitely "enough gun" for most applications.
Even with the 125gr. supersonic stuff it's easy on the ears, much quieter than 5.56.
I'm a fan.....

Reloading may be the best way to go for me. I'm having a lot of problems finding the ammo I'm the local gun shops

this is the best pic I have of it at the moment

A lot of knowledgeable shooters consider the .300 an inside 100 yard round that should be zeroed at 50 yards. OTOH, it has an effective range of 460 yards out of a 16" barrel (440 yards out of 9"). Still, the round drops significantly at distance making accuracy difficult out there.

First I've heard of the .300BO being anything like .308. It's usually some other cartridge that is constantly compared.

As for all the potential ability of the AR to change and morph into another gun, it's rare that any one does it. A rifle built and outfitted with stock, grip, optic, handguard, and flash hider for long range won't get a different barrel just to allow it to use a short range one. The result starts looking like one of those internet carbines, and it would have all the wrong parts on it.

For military purposes, 5.56 does a nice job, given some parameters, exactly the same as the others. We get to pick and choose - they don't - and in some limited cases one is better than the other. Rather like choosing how much car you "need" to get around to work and in life. Plenty do quite fine with ones that others can't abide. Cars are like that, guns are like that, cartridges are like that.

Hopefully we aren't kept from using one because it was made illegal.

Nice looking rifle. What do you want to do with it. Plink? Hunt? Something else?

I really like mine. It also has a 16" barrel. No tax stamp needed. It is comparatively cheap to feed and very fun to plink with. It would definitely take down Alabama deer at the ranges I would normally shoot where I would be hunting. It's no bean field rifle, that's for sure, but at 100, maybe 150, yards and in I would not be afraid to shoot a deer with the right load. I would be very comfortable at 100 yards and in, and at 75 yards and in I would be shocked if it failed. Shot placement being good of course.

I enjoy plinking with my 5.56 AR, but also with my 300 BLK AR, and they are so different from each other it is a nice change of pace when switching back and forth.

You can shoot .300 Whisper in 300 BLK barrels, but not vice versa.

I like being able to make 300 BLK cases from free range brass.

Right now I plan on using it for plinking but down the road it may turn in to a hunting with it. I really enjoy cyote/fox hunting, any experience with that using the blackout?

I thought the 300 Blk would just be a short lived fad......I guess I was wrong but I still don't see what the appeal is.

I dunno man, the free brass kind of got my attention.

 

[hso]

I'm not sure that the accuracy and range make it suitable for coyotes, but if you can call them in within 100 yards it will do the job.

 

[justice06rr]

Essentially a .45 ACP in an expensive rifle. Why not practice and learn how to shoot your government .45 really really well?

That is not exactly accurate.

The rifle can be as cheap as any AR15/M4 style rifle. I have built them for under $500. Many 1911's and 45ACP pistols (Sig, HK, Kimber) are much more expensive if not just similarly priced.

Also Rifle > Pistol

There are many merits to the 300BLK round, particularly in suppressed and short-barreled rifles. The only main drawback is the higher price of the round and limited availability. If you handload, that is eliminates that issue.

 

[bluetopper]

For a 223 wildcat cartridge the 7mm TCU can't be beat in my opinion; so very accurate and quite a bit more power than the 300 Blk. You don't cut any of the 223 case length off just neck it out to .284.

I've made a many of them from 223 brass throughout the years.

Yes I have heard that from many people, seems like it is still going to be a nice plinking gun

Not a fad, but more of a round for those that suits the caliber's benefits. Its the same as any other non-common round i.e. 6.8SPC, 6.5G, 450Bushmaster, etc.

I'm not sure that the accuracy and range make it suitable for coyotes, but if you can call them in within 100 yards it will do the job.

I believe it is capable of around 200yards or more with the right bullet.

Plenty of ammo in stock at Midway:

Here are some good articles for those not acquainted with the caliber:

http://www.gunsandammo.com/reloading/6-reasons-reload-300-blackout/

http://300aacblackout.com/

from the above:
"At 300 meters, 300 BLK has 16.7% more energy than 7.62x39mm. Max effective range, using M4 military standards for hit probability, is 440 meters for a 9 inch barrel, and 460 meters for a 16 inch barrel. 300 BLK from a 9 inch barrel has the same energy at the muzzle as a 14.5 inch barrel M4, and about 5% more energy at 440 meters - even though the barrel is much shorter.

For hunting - think of it as like a 30-30 but from an AR. After you are done, you can remove your 5-round magazine and put in a 30 for plinking or home defense. For ammo, Remington has you covered with the Premiere AccuTip 125 grain. Want industry-wide support? Over 60 companies have already announced or sell products."

Right?
Oh and my Ar 15 in 300 Black cost me $500. I have more than that in one of my 45's

Okay, Red Herring on the field.

You aren't just going to go from shooting 125gr @ 2100 fps to 220gr @ 1100 fps. You have to rezero the gun between switching loads or you won't hit anything.

Second, you may have gotten a basic non-free floated upper without a bolt & carrier assembly or sights.... or you may have gotten one heck of a buddy deal, but your average person is no way getting a complete .300BO rifle for $500.

No Red Herring here. But I do need to clarify. I dont shoot subs my self.
I shoot 125gr jacketed @ 2100 fps and 155 gr cast at 1750fps.
Zeroed at 100 yards for the 2100 fps load and just aim up one mil dot for the cast load.
Some times I will zero for the cast load if thats what I am shooting most. Then just mil down for the jacketed.

And yes I did build my 300 for around $500.
I am a sale buyer. I got three lowers for $75, built two and sold one for $75 when they got pricy.
I got the upper on sale complete with the BCG for $299

Just have to practice good buying techniques. When its cheap buy a bunch. When its expensive sit on your hands or sell some.
I have way to many wants to spend all my money on just one.

The 300 is the one on the bottom.



They may be Frankenstein builds. But they shoot just as good as any others costing twice or three times as much.
20 round mag at each aim point.



Also none of my AK's will do what the 300 Black out did above. So they are not only a fun gun. You can actually hit consistently were you want to hit.
Not that AK's are not fun. I like them too. But it is fun to place 10 clay pigeons on the berm at 100 yards and pop them all with out missing.

I'm not sure how you got that buck to pose with your rifle like that, but I don't think he trusts you very much ... He seems to be keeping an eye on you

When I first started reloading for 300BO I bought a 2K of new 147's thinking I could load some for sub-sonic and others for super-sonic ... I haven't had much luck finding any sub-sonic loads, or maybe I'm just looking in the wrong places. I know it's generally accepted that 220's are best for subs, but I'm just killing paper and have no intention on any tactical uses for the gun ... I have both a 16" and a 10" and use a 30 caliber Phantom Ti suppressor

 

[Pilot]

I'd like to get a 10.3 inch barreled SBR for 300 BO. I think it would make a heck of a carbine, and I would reload for the caliber. I have put this on the back burner for now as I just bought a GI M1 Carbine, and will be reloading for 30 Carbine with somewhat similar ballistics, although I think the 300 BO has it beat by a few hundred FPS.

 

[farmerboy78]

The only comparison that the 300 blackout has to the .308 win is a .308 bullet leaving the barrel... I had both, a savage 10 pc .308 and a custom savage 300 with a krieger barrel...sold the 300, it's performance lacked to say the least... it's accuracy hurt past 150 yds due to the trajectory of the round...I could do everything with my .308 win that the 300 could do, and still shoot beyond 500 yds accurately and confidently...but, I will give the 300 this...it would be a great round to start a child with because of recoil if you had to use a 30 cal weapon. Just my 2cents!

 

[Walkalong]

Not yet, but this load should work for Coyotes at reasonable distances. My barrel also loves the 7.62 .310 Z Max. (Make sure the chamber neck is large enough)

 

[cfullgraf]

I have enjoyed working with the 300 BLK. Reloading makes ammunition as cost effective as about any other reloaded ammunition. Cases can be easily made from 22 Remington cases if commercial cases are not available or considered too costly. I shoot only supersonic

Another use for the 300 BLK.

I feel that an M1 30 carbine would be a good home defense rifle. Handy size, good performance at shorter ranges. But I would not subject a fine old USGI issue M1 carbine to that service. Also, most of the commercial offerings are less than reliable for the task.

Enter the 300 BLK. Similar handy size as the 30 carbine, a little bit better ballistics, reliable shooter, and a modern rifle with available spare parts.

Sighted to 50 yards, I can get small critters on my farm out to 50 yards and larger critters out to 100 yards. The rainbow trajectory out past 100 yards limits the risks.

Not a be all to end all, but a300 BLK is a good alternative to consider.

 

[Pushrod]

If you are looking for pre-loaded 300 BLK subsonics (220 gr. matchkings) FOG firearms had great prices on their ammo and always has excellent customer service.

For zeroing the subs, zero your firearm at 10 yards. It will be right on again at 100 yards.

 

[mjsdwash]

it allows the use of cheaper cast bullets if you reload. with the heavy bullets you can cycle the action, without horrible leading. Or you can use jacketed bullets and get something a little better than a 30 carbine. I mean that in a good way

 

[hso]

I like the fact that I can switch the barrel and have it set up for a 5.56.

You want to just switch the upper and not the barrel. The gas systems need to be different and you'll find changing a barrel out to be a much bigger issue than pushing two pins and popping the top off for another.
