.300 blackout

[cfullgraf]

Walkalong: You can also use the factory Hornady 300 Whisper load in a Blackout

Yes, 300 Whisper data has given me many a starting point for my 300 BLK loads. But, more and more 300 BLK loads are available now.

110 Hornady VMAXs shoot great. But, I really like Speer 125 TNTs and Hornady 155 AMAXs.

I have been happy with W296/H110 and 2400 for the lighter bullets and AA1680for the 155 grain bullets.

I have shot a variety of bullets up to the Missouri 240 grain cast bullets. Without a suppressor, i never got the heavy bullets, 200 grains and over, to completely cycle the action including HSM 208 AMAX factory loads. But do the heavy bullets ever hit the backstop with a good thump.

I just ordered an AAC single chamber muzzle brake to put on my 16 inch, 300 BLK, barrel. That will make the rifle quite handy. I have the 223 Remington version on a 16 inch 223 Remington AR and I like how it works.

I like having to worry about only one rifle.... All the way to 350 yards

Really you're gonna limit a 300 to 150 and now your pet 6.8 is good to 350. My god pour me one. At 350 yards a 10mph wind is a little over a foot of drift for your 6.8, missreading the wind 5mph at that distance could lead to a gut shot animal now add in marginal 850 ft lbs.

I have a 16" and a 8" AR chambered in 300 blackout. Where it shines is in short barrel. A 10" 300 BLK has the same energy at the muzzle as a 16" 5.56 M193. Not only that, I can shoot suppress and I can shoot bullets 110gr to 250gr. I can't say that about my AK or my 5.56 AR. At 300 yards, it still has more energy than a 7.62x39 or 5.56.

Watch Travis Haley discussing the 300 BLK and hitting targets at 750 meters with an aimpoint.

There is wind drift with all calibers, so your statement is exactly what?

That happens with the 22 caliber all the way to a 338 Lapua.

Any shooter needs to take wind into effect on long shots............


I do thank you for pointing out the rule of thumb for humane shots at 1000 ft/lbs, it did get me thinking, and was the basis for most of my replies.

I do think that an animal can be harvested at a lower energy level than 1000 ft/lbs, but I do believe, I wont be going out as far as I would have for hunting, if the shot presents itself, as I would have before this.

My new max shot on animals will be 350 (maybe even a little less) vs 400 with my 6.8



The 300 BLK has many positive factors, but its not a solid 200 yard hunting round as you have stated, at least not yet, or at least any bullets that I can find today

The 300BLK is newer, so maybe there will be a new bullet / barrel / powder combination to get it to and past 200 yards. (New products for 6.8 have increased performance over the past few years)

At the end of the day, the two calibers, three if you count the 7.62x39, all have their place.

Its an apples to oranges comparison.

There are positive but different attributes for both calibers

I will probably get a 300BLK barrel the same time I get my 223 upper, just to get some of those benefits. I would love to load for cast lead for the 300 as well as shoot suppressed (never lead through a can though) so my interest in the 300 would be shorter distances, where it shines today

But for now, for me, for hunting at longer distances up to a certain point, the 6.8 is my choice.

Take care, and have fun with your 300BLK

the blackout had the bad luck of being started right at the beginning of the ammo hoarding/disaster. it is a good idea but is has been hampered the insane buying tactics of the shooting public

 

[itsa pain]

Heavy and slow, the .300 Blk would seem to be ideal for cast bullets. Imagine plinking for 15 cents a round using cast bullets and exclusive of brass . When things normalize I will pick up dies and a barrel (I already cast 160 gr .309s for my 03-A3) for my AR.

since you need a dental hygienist to clean an AR with regular ammo I would hate to clean it after lead bullets being it might clog the gas port

 

[mavracer]

That there is more wind drift to deal with at 350 than there is at 200 yards. Making a 350 yard shot on a animal in field conditions is more difficult than a 200 yard shot.
A 5mph wind gust drifts my 300 Blk less than 3" at 200 yards. A 5mph gust moves your 6.8 nearly 6" at 350. Assuming both guns are capable of MOA accuracy. I'm going to be within 4" of point of aim(2" group centered 3" from POA) at 200 yards, where as you trying for 350 with a 6.8 can be pushed nearly 8" from POA (3.5" group centered 5.8" from POA).
So my point is your 6.8 is in no way a ethical 350 yard deer round as it involves too much hope and prayer. The further out you get the less room you have for error.

Hope and prayer? Have we stayed that far from shooting skills in a rifle forum this is considered hope and prayer? It may be unethical in your skillset, but don't project that to everyone. This might just be comedy enough to get me through the week.

Respectfully,

I think we will have to agree to disagree.

Have a blessed day, and have fun with your 300BLK

[Elkins45]

I'm a fan because I can shoot cast bullets through my AR with only a change of barrel, some surplus 5.5 brass and a new set of reloading dies. There's just no substitute for trigger time, and I figure my total cost is somewhere around $0.10 per round for my homemade 300 ammo. That buys a lot more trigger pulls per dollar than buying jacketed .223.

 

[mavracer]

There are factors beyond your control as a rifleman at 350 time of flight for a 6.8 at that distance is just over 1/2 a second on a animal that is easily capable of 44 feet per second (30 mph).
Part of shooting skill as a rifleman is knowing these factors.

It may be unethical in your skillset, but don't project that to everyone.

The only thing I am projecting to everyone are factors that apply to everyone.
350 yards is a harder shot for everybody than 200 yards is.
Wind affects everybodys bullet more at 350 yards than 200 yards.
Every bullet will drop further at 350 yards than it does at 200 yards.
Standard deviation will be a larger factor on drop and wind drift at 350 yards than at 200 yards.
Trigger control and breathing won't change these facts.
At 350 yards with a 6.8 you're hoping the wind doesn't gust and praying that the animal doesn't move.

I think we will have to agree to disagree.

Ok so you think you have more room for error the further out you go.
You are correct I dissagree.

Try posting this again

I posted the name of the company that I got the 300BKO from and that post was 'MIA' for some reason ?.

The company that is from Texas is Right To Bear Ammo [ www.Right2Bearammo.com] .

They seem to be loading and selling their own ammo LOADED and manufactured in the U.S.A. [ according to their box ].

I was not interested in the 300 Whisper as my state is THE nanny NY .

So I saw no need for the MUCH slower round at all,this is to be a game rifle and I am very happy with their posted chrono stuff,AND even happier with the accuracy of the stuff.

Since the ammo 'shortage' I have been able to receive a few hundred rounds and that was why I felt comfortable to shoot it up.

I do not reload and have not for decades,NOW this round and the 30-30 are making me look at doing so.

elkin do you find the lead bullets clogging the gas port? or are they hard enough to cause no problems

I don't shoot the .300blk but know several that do. From what I've seen the only real advantages it has is it works well with a silencer and it's bigger than a .223 with only a barrel change. Personally I'm a 6.8spc guy and IMO its a far superior round than the .300blk. But I know several folks that have taken to the .300blk for 3 gun use and really short range deer hunting in the thick stuff. It's a one trick pony IMO and since I don't clear houses in far off lands and shoot BG's quietly at room distances I don't have a need nor use for it. I could see it as a good choice for a Handi-rifle chambering in a youth gun though for a new/young hunter looking to bag a deer inside a 100yds.

One trick pony?

lets review again:
1. Fully interchangable with AR platform except the barrel
2. Works well suppressed or unsuppressed
3. Works well SBR or standard 16" barrel
4. Excellent for reloading coming from 5.56/223
5. Standardized by SAAMI

The only downsides being the short range and ammo price. 6.8SPC is slightly cheaper but at the cost of different parts you need to buy. If I needed more range I'd go directly to a 308...

Yes I have considered 6.8 for my current build but really don't see the value when I can buy a more available .308 rifle instead.

 

[PapaGrune]

I have a friend that already has one, he is a PO LEO. He is building one that he can show his chief as a possible ar-15 replacement. He is going all out with a suppressor on it. They could use as a sniper rifle, but is looking at it as a trunk gun like the ar. That they already use. Not a large metro PD

he could put that to good use sniping people that do not have their seat belt on lol

 

[Dolph92]

I have been messing with some 300BLK loads anything from 110 grain to 130. I have a particular load of a 130Gr Speer Hot Core #2007 doing about 2400fps out of my 16" 1-10 twist Red X upper. I have been really impressed with this and if the accuracy is there this is what I will be using for whitetails this fall. I will also be doing some gel tests on it as well soon here just because I am a data freak and think it would be fun to do. I will post up my results as soon as I can.

 

[Sapper771]

Recoil is similar to a .223/5.56. It feels like it has slightly more push. Accuracy is decent so far (IME). I have seen some very impressive groups from others.

What I got is a more powerful cartridge in the same AR-15 platform without having to change much. All that is needed is a barrel or upper. Same mags, same bolt, and 223/5.56 brass can be easily converted to 300 blk. Can use any .308 bullet from 100gr to 220gr (twist dependent).

I was also looking at getting another AK, but at their current price, I saved money by going to 300 blk. 300 blk from an AR is more accurate than 7.62x39 from an AK. 7.62x39 is cheaper and more available than 300 Blk, but 300 blk is easier to reload. 7.62x39 is more powerful than 300 blk, but not by much and only within 100-150 yards. I feel that the 300's bullet selection is a strong pro.

 

[Richard Head]

The 7.62x39 is a decent enoughe round though it's nothing special. It's the rifles such as the AK47 and SKS that shoot the round that are junk.

 

[Art Eatman]

Sorry, Richard, but "junk" is not correct. Ugly, yeah. But they function very reliably and are sufficiently accurate for their intended purpose as a close-range infantry weapon.

 

[Grassman]

I just got my 300 upper this week, can't wait to find some ammo and shoot it up.

 

[gspn]

The .300 Blackout (and it's ballistic twin the .300 Whisper) are the result of companies developing new cartridges that fit into AR-15 magazines, and which can be optimized for running heavy bullets at subsonic speeds for use with suppressed rifles.

That is the best and most efficient summary I have ever read on the topic.

 

[dhopson]

Just an FYI on this thread, I built a 300 BLK (7.62x35) and love it. I used a CMMG upper and Spikes lower. I have never, and hopefully will never buy a round of ammo for it (about $1.50-2.00 a round). I have several thousand .223/5.56 cases and I go to town with my Harbor Freight mini cut-off saw and dies. I use the Sierra 2120 125 Gn PSP bullet. I started loading them with the LIL'Gun receipes, and then worked up an Alliant 410 load of my own. 14.1 grains cycles and holds the bolt (also no signs of overpressure on the primer). I estimate about 1,750 fps (don't have a crono, using data from similar loads). Dead on accuracy also. I must admit, I also like the idea of having the ability to use components from different platforms (AR, AK, SKS, and 410 shotgun - all of which I reload) to create my ammo. Might just be helpful in a pinch. Anyone wanting info on my A410 load, let me know. It works great in my AR; but, use it at your own risk.
