9" 300 blackout pistol worth it?

[Flopsweat]

Since the other choice I have is 12.5 then I guess that would end up being the best overall one to get?

Yes if you want to shoot out to or beyond 200 yards. No if it's just for home defense and 100 yards or so. I would bet the 9" wouldn't have much drop at 100 yards. I've shot a 10.5" at 100 and it sighted in like a 5.56 would, so not much drop. Looking at that chart, about 1000 FPS with a 110 gr 30 caliber bullet, I would expect it to drop a lot by 200 yards, just as a guess. I never took the 10 past 100. Ask the guys with the 9" and under barrels here what results they've gotten at 100+. The 14.5" had very little drop at 200 yards and I don't think I ever had it out past that.

I've got one with a 8.5" 1:7" twist barrel. No suppressor, yet, but hopefully someday soon.

I haven't bought any ammo for it, only loaded my own. I've got 110gr. JHP and 160gr. and 230gr. lead bullets that I cast and powder coated myself, and I've still got about 40lbs of lead alloy ingots to make more. Only thing keeping me from loading more is the cost of small rifle primers. I'm not going to pay mouth-breather-toilet-paper-hoarding-idiot prices.

How much does it drop from 100 to 200 yards? With say the 110 or 160 gr?

With everything that's been going on lately, I haven't had a chance to shoot it much or at any real distance yet. Closest range is 35 miles away (membership only) and the shooting areas that are closer to me are only 50-75 yards. Not sure the cost of membership is worth the price since I doubt I'd go more than 2 or 3 times a year. Since I don't plan on using it much beyond 100 yards anyway, I don't really care about the drop beyond that. I have other rifles for shooting longer ranges. Handguns, too, for that matter.

I loaded the 110gr with the thought they'd be a reasonable choice for coyotes called in close. The 230s are for the suppressor, should I ever get one, and the 150s were for general shooting/plinking. They seem reasonably accurate so far and function without any issues that I've noticed.

There *is* a place in town that calls itself a shooting range, but I'm not sure a 4-foot-high berm of rocks in an open field 100 yards from a rickety table really qualifies, but that's all I can see from the road driving by.

8.5" pistol gas that eats every thing from 110 to 220 no adjustment
16" carbine gas eats all supers but can be picky on subs based on the powder choice
if you reload great if you don't well then it will cost you $$$$$
but i can go and get just about any 308 bullet and load it for 300 blackout 110 to 220
but i am sure by now you have your mind made up and 4 pages should have done it by now...
unless you want to start a comparison between 300 aac 223 or 556 and 7.62x39
or even compare it vs 9mm or 40 or 45....

I am always interested in learning as much as I can..

I used to keep one under my bed. Great HD setup with SD ammo. It cycled everything but subs reliably but I already knew that before I built it. Only thing that has pushed me away from .300blk is ammo price and availability.

did i ever tell you i got that barrel to cycle reliably? gas port was undersized. pretty common of ballistic advantage barrels in my experience. love their barrels though!

Are you referring to the one I built the upper for? That was a BA premium SS 7.5" Hansen profile.. a rare barrel. they don't make anymore. I really liked that build..had a cool fortis rail if I remember correctly. the only reason to shoot subs is if you're running suppressed anyway, and with a can it probably would have had enough back pressure to run just fine. Did you get rid of it?

Well That answers that… Cool, it stayed in the family so to speak

Honestly I have had a 300 BO since January of 2012. I bought it for the fact that I eventually wanted to put a can on it. The round was developed by Silver from Advanced Armament Corporation. A customer that was part of one of the special operations groups went to him and said that they wanted something with more oomph then a 556 SBR or the 9mm. The goal was to be able to run it suppressed or not and have the barrel less than 16".

The 6.8 spc and 6.5 Grendel were already out but they didn't use the standard AR bolt so that's not what they wanted. The only round that was similar to what was required was the 300 whisper. It was a wild cat round and therefore was not SAAMI approved.

300 BO will run from 7"-16" but ideally anything from 9-12" is just fine. Price of ammunition has always been a sore spot unless you reload. Super sonic is 110-125gr and is good to about 500 yards but usually only with a 16" barrel with a 1:7 or 1:8 twist. If you plan on only going out to 300 yards or less then 9-12" will work just fine. Out of a 16" barrel with 1:8 twist and shooting Hornady 110gr GMX I would get 2300 FPS, 1300 ft/lbs of energy at the muzzle and at 300 yards it would drop about 13-14".

I currently have a 10.5" pistol with a 1:8 twist and it eats everything and I can nail anything within the 300 yard line. No need for a heavy buffer or different spring unless you want to reduce the more than bearable felt recoil. However, if you do then you will be spending time and money trying to get the right combination of ammunition to buffer, recoil spring and gas tube length. But that's your choice. Excellent round I say go for it!

BTW mags can be a pain in the backside so I suggest you get the Lancer ones meant for 300 BO! Also I think my Duramags for 300 work great too… just been a little bit since I shot it lol!

@RobMa

However, this does not mean that I'm an expert in the round but I have experience with it over the past almost decade.

Ah shoot sorry @Mygrainman I got sidetracked and forgot to reply. Yes, it indeed stayed in the family!

 

[RobMa]

I have read you need 300 BLK mags as well??

 

[Mygrainman]

I have read you need 300 BLK mags as well??

They help, but are not completely necessary. One advantage is they help you to keep from putting 300 in your 5.56 or vice versa. I have a couple "300 BLK" mags but I really haven't noticed any difference.. I prefer regular magpul 20's, helps keep down on Ammo consumption and easy identification.

 

[v0lcom13sn0w]

i use fde pmags or black hexmags for 300blk only.

 

[Geardo]

I have a suppressed 8" for a dedicated HD and car camping gun, and I really like it. Fits in a banjo case with the Can, and my wife can even use it.

If just using it for subsonic I think its silly, but the 110 grain Vor-tx is downright spicy, even in the 8" barrel.

Its only worth it over 5.56 if you go really short IMO. 11.5+ I would go 5.56.

 

[Flopsweat]

I have read you need 300 BLK mags as well??

I have had feed issues with some standard mags, but only when loaded full. To be clear, I normally load 5, 6, 10 or maximum capacity. I have some AWM mags with steel feed lips that run flawlessly and have survived numerous drops while fully loaded.

To me, the best reason to have a different brand, as mentioned earlier, is so that you have a strong visual cue that it is not 5.56. I have witnessed a kaboom with 300BLK in a 5.56 gun. Toasted the gun but only minor wounds to the shooter. Scared the dickens out of everybody though.



edit: sp (can't manage to spell the brand name correctly)

 

[AK0perator47]

So I'm going to show you a couple of different pictures and then explain why I suggest you get the right mags for a couple of reasons

.
So, you can see that I have 2 different manufacturers. And then there's the inside of normal AR/5.56 mags. They have the front part that is indented because of the shape of the 5.56 round. It's necked down. The 300 BO is almost not at all necked down. What happens then is it pushes the round over and causes it to malfunction.

Yes, you can drop off the number of rounds or get a 20 round mag etc… but why? I like 30 rounds and why limit myself?

Next is the rubber bands that I put on the bottom. Along with the different textures of the mags. Easier to identify and even in the dark. My Hexmags have 110gr HP and the Lancers have 110gr FMJ. ALL MY MAGS ARE LOADED WITH 30 ROUNDS!

Yes I see, this is very helpful!

Thanks! I will not forget all the help you all have given me...

@RobMa

My main 300 BO pistol. Of course everyone does the whole Frankenbuild BS but whatever. I look at it like this… does cars come in only one trim? Nope. Why? Because people have different tastes. It's just like why there are so many manufacturers and models of firearms. Anyway on to the 300 BO porn! lol


Yep 30 rounds in the Lancer and I use dust cover for all my rifles. The upper is no longer made.

Is that a linear comp on the end?
