So, I’ve been looking at possibly adding a .300 blackout pistol with a 7 inch barrel.

I currently do not own anything chambered in 300 blackout, nor any ammo at the moment. Unfortunately, I would say there’s only about a 20% chance at adding a suppressor unless the HPA ever passed.

It would fill the spot of a bedside/ backpack/ truck gun. I’ve also heard it can be useful for small game (with supers) but not sure how humane it would be on deer.

What say you? Does a .300 blk in that size make sense? Would it be any better than an 10.5in 5.56? Or would you recommend something in the effect of an AR9/ Mpx, etc?
 
.300BLK is a great round & a 7.5" AR would fit your parameters perfectly.

@rantingredneck has taken several deer with the .300BLK & will hopefully chime in with just how effective it is on deer.

I've got a 10.5" .300BLK, but have a suppressor in jail & will be installing a 8" barrel to keep the OAL as short as possible with the can mounted. I imagine it as a 'bump in the night' gun. I've not taken any game with it, but I can ring an 8" gong at 100yds with a red dot sight.

They're fun guns & you'll be GTG with a 7.5" to 10.5" .300BLK.
 
I've an 8.5" pistol & a 10" SBR. For a short barreled hunt/SD gun I'd rather have the BLK.
16"+ probably a 5.56.
 
I have a 16” rifle and a 10” SBR, but have a braced lower I can move that upper to.

If you want to try one out, let me know. Just buy some factory ammo and bring it/them back when you’re done. If I was able to go to the range at the same time, I’d bring some silencers for them as well.
 
Without a can, it just seems... dumb.

I have two of them now, and without the can on them they're just funky 30 cal 762x39/30-30 power levels in an AR package. Great if that's what you want, but if I was hunting in that power range I would rather have a lever gun, and if I was using it for defense I would rather have a rifle in 556 as ammo is WAY more plentiful and you could actually throw a few thousand rounds through the gun practicing without breaking the bank.
 
.....10.5 inch barrel if for subsonic ammo only....16 inch barrel if you plan on using supersonic ammo.... Or both.

Short barrel with supersonic ammo.......really loud and you lose some velocity.

Long barrel with either ammo....no problems.

Its just a personal preference.
 
I have a 10.5" barrel blackout pistol that I use to hunt an area that doesn't allow rifles, it's also the gun my 8 yr old daughter hunts with. MUCH quieter than a 5.56, even with supersonic ammo. The blackout is perfect for short barreled setups and typically only needs 9" of barrel length to burn all the powder. We've killed 2 deer with it and neither have taken a step.

I have two 8.5”, one meant to be suppressed the other with a tucked flash can. While some believe that .300BLK supers are silly, I find it to be an excellent, and superior, alternative to a short 5.56. I can shoot a bullet double the weight at about 75% the velocity netting me 20% greater energy in a shorter barrel, built on the same AR platform. .300BLK is meant for short barrels, .223 becomes a flame thrower at 10.5” and below. Plus I have the ability to switch to subs that will function reliably with only changing a mag.
While changing from subs <—> supers is equally as easy with 9mm, the .300 will have better energy and with supers far better energy and range.
However, I wouldn’t buy a .300 if I didn’t reload as factory ammo a little pricey IMO.

.300 is the way to go for short barrels. 8.5 and 5” here. The 5” doesn’t spit fire and doesn’t even have a flash hider. It shoots supers fine. I have not tried subs on it yet.

Those lengths on a 5.56 would be unpleasant, if not to you then other shooters.
 
I have two 16" rifles in .300 BLK that my son and I hunt with. They've become our go-to rifles the last several seasons and it's not from lack of choice. There are plenty of .308 and .30-06 options laying around here, but why?

-NC Whitetails aren't that big.
-The central part of NC Where I hunt is mostly woods and creekbottoms and a 75 yard shot is a long shot in that territory.
-110gr Barnes tipped TX bullets exist and are perfect for deer.

I have a 10.5" pistol that is my SHTF trunk gun. You don't lose a lot of velocity going from 16 to 10.5" in supers in .300BLK and the flash and bang isn't nearly what it is in 5.56 in a short barrel. 110gr. Barnes Tipped TX or 110gr Hornady Vmax are ugly antipersonnel rounds.

A note on the 110gr. Vmax..... it was originally designed for .308 velocity, so at .300 BLK velocity you still get quite devastating expansion/fragmentation but you get a little deeper penetration as well. I've taken a few deer with that bullet. None took a step, field dressing was impressive.

I've not taken a deer with the 10.5" pistol yet, but will. And I have no qualms about it working within the ranges that I hunt and with the ammo I've selected.

I found the .300BLK to be an excellent deer cartridge, using factory Remington Hog Hammer ammo. This photo is of a venison ham I smoked for Thanksgiving after dropping the buck with my home-assembled rifle.

Thanks for all the info! The 300blk I’m looking to get is currently OOS, but I hope to pick one up soon.
 
Instead of starting a whole new thread thought I could ask it here first. Just finished my 300blk build. Just curious what (relatively) cheap plinker ammo you guys use. One day I'll get into reloading but not there yet. Preferably store bought ammo not online buys

The bullet weight w supers and the potential if I ever take the can plunge is why I built mine. And the ammo will get cheaper when Wolf release their steel case.

Usually just whatever is the cheapest on the shelves, but Wolf is going to start producing steel cased ammo for it this year so that is what I will be using for playing around on the range with.

ammoseek.com can become your friend. There are some a bit cheaper out there than OL, but I have had luck with Precision One and with PPU
 
I bought a 300 upper with intention of making a pig gun(built an ar-10 later). I got such a good deal on the upper I couldn't pass up the idea. Its a 16 inch barrel DB that cost me under $200 shipped with BCG and free floated hand guard. I really wasn't in the market, but the sale price got me. I have yet to shoot anything besides paper with it, currently set up to shoot 115 Barnes TSX2. I need to chrono my loads. At the time, this was the best option for an alternative to 556(6.8 took to many differnt parts, same with 6.5 Grendal). I don't plan to run a can or shoot subs. Before I built the AR-10, this was going to be my primary pig gun, it still may end up that way due to the weight difference with the 10. If I were looking for a truck gun( I may be depending on how popular the caliber gets), I'd build a 350 Legend pistol with a 10 inch barrel. I'm on the fence right now till I see if the 350 has any staying factor, I already have a couple odd ball calibers, don't need any more. The round makes better sense(excluding subs with can) than 300 Blk for personal deference, short range use, and hunting out to 150 yards. We will have to wait and see. Ammo prices are defiantly within reason, already seeing uppers on the market( a little high priced right now)

Yeh I think I'll stock up on some wolf when it comes out. One site has it listed already but says out of stock. Currently listed at .20 a round

I usually shop sgammo.com they have plenty of 300, but teh best price they list right now is $.48/round
 
300 BLK with proper bullets is extremely effective CQB. I have nearly 2 dozen 300 BLK from 7-8.5 inches to 16 inches, and two bolt guns. Have done extensive load data and pressure data, and terminal ballistics with several bullets.
We designed a 100 gr CEB Raptor specifically for the 300 BLK some years ago. This bullet was such a success on everything from deer/hogs up to Black Bear, this is the only bullet I load anymore from 300 BLK to 300 Winchester, and will do everything you need or want to do and more for anything you are going to use a .308 caliber bullet for. It is very successful in 308 WIn as well and has accounted for more DRT animals than you can count.

We keep pressures to 55000 PSI for this cartridge. In 16 inches we can run the 100 Raptor to 2550 fps, as we drop down to 10.5-12 inch guns that runs from 2380-2420 fps, dropping to 7-8.5 inch guns you are at 2275-2300 fps. I prefer 10.5 inch guns over the shorter versions for better terminals, although not coming up too "short" with the 7-8 inch guns... Pun intended.......

The only other bullet that meets my criteria for tissue destruction and penetration is the Barnes TAC designed for the 300 BLK as well. At 16 inches and 55000-56000 PSI this runs at 2400 fps, 10.5-12 inches 2250-2280 fps, and 7-8.5 inches 2170-2200 fps.

Why anyone would purposely choose the 300 BLK for Suppressed work I don't know, there are far better choices out there. Now you would have a .308 caliber handgun cartridge? None of the standard .308 caliber bullets are terminally viable at Sub Sonic? None are stable once terminal penetration begins. Choices for bullets that actually are terminally viable at Sub Sonic are specialty bullets that you can get from Lehigh and Cutting Edge, and are expensive, and still only .308 caliber. In my opinion, 9mm Sub Sonic is far superior to .308 caliber Sub Sonic when it comes to Terminal Performance. With the exception of the bullets designed for Sub Sonic work. I have worked with JD Jones on these projects with special bullets in years past and they are viable. However, I doubt seriously that many of you are serious enough about Sub Sonic to go the distance and work with Sub Sonic designs???? Instead, working with simple standard .308 caliber bullets. If so, then 9mm is far superior in that department simply because of caliber and stability, once terminal penetration begins. At sub sonic .308 caliber bullets do not expand, they are not terminally stable, they tumble upon entry, penetration is poor, and terminal paths are unpredictable. And no, tumbling is not "Terminally Viable" or nearly as destructive as decisive and true penetration, and expansion or non conventional tissue destruction. One reason JD and I were working with better bullets in .308 caliber at Sub Sonic was for various State Dept that were charged with "Deer Control" in urban areas. Standard .308 caliber bullets were causing more issues than the solved at Sub Sonic levels. JD and I worked with bullets that would fragment at Sub Sonic velocities in the nose section, and then allowing a solid full caliber base to penetrate deeper, and straight. Causing far more trauma to be inflicted, and therefore better terminal results. This initial work was very successful and therefore carried over to the bullets you can get today from Lehigh and Cutting Edge, and probably some other places as well. In these cases, then Sub Sonic is a viable option for 300BLK.......

For my use, I much rather have that 100 Raptor loaded for any serious work, or for hunting. It is well proven. I keep a 10.5 inch gun close at hand. Although, I do admit, I don't feel under gunned with a 8.5 inch gun on the boat.

The 300 BLK is a superb hunting firearm for kids and women as well. Loaded with Raptors, the cartridge is extremely effective as well. It's not loud and no recoil at all. A friend of mine in NC has some young boys, age 8-10, and not all that long ago his 8 yr old shot a nice bear with his 300 BLK and the 100 Raptor load. Bullet went thru heart broadside, exited, bear took 1 step forward and DOWN for the count on the spot. In addition they have taken several deer and I hear even a few alligators as well...... Perfect for Kids and the Ladies as well as grown men...........

Currently I am having SSK build a 7.62X40 for my daughter and her future deer hunting. 7.62X40 is a longer 300 BLK, and about 200 fps faster across the board, still no recoil or noise and works perfect in a Winchester M70 that was chambered in 223............ Oh, and it will be loaded with 100 Raptors at 2800 fps.................
 
The Wolf is 147gr. Wonder why? It's already down on velocity vs x39 at similar weight, this stuff doesn't even break 2000fps. I'd rather have 125gr if I'm shooting supersonic.

Awesome! Where can I get these Raptors, and how much are they?

I promise you there is nothing like them. I know. Not cheap, want cheap look somewhere else. Performance, well I will put it this way, you have never seen anything like it. I know, because that is the standard saying from everyone that studies Terminal Ballistics......... "I have never seen anything like that"................ I have heard that 100s of times believe me..................

I order BULK, but I also get a huge huge break on the bullets, 10% above cost, since in the beginning I helped develop the entire line of Raptors. My last 100 Raptor order was 2500, the one before that was 4000, so yes, I believe.

probably so they can share projectiles between their steel-case .308 and this, makes it alot more financially feasible.

I've shot 147s from my 8.5" pistol, they work. I have heard that subsonics are coming mid-year. At 20 cpr for plinkers I'm not going to complain. I can make my own light or heavies.
