Tell me about the 300 blackout
Posted on 12/14/16 at 8:32 am
Posted on 12/14/16 at 8:32 am
Just picked up a NIB AR in a trade. Already have one that's decked out and that I shoot often in 223, so I'm thinking about an upper in a different caliber for hunting. Looking hard at the 300blk, but like the ballistics of the 6.5 Grendel better. Max shots where I hunt are around 200 yards.
I feel like the 300blk would be better for availability of ammo, and ease to suppress if I wanted to.
This would be basically just for hunting deer and pigs. What say ye?

Do it

If you are looking for something to suppress get the 300 blk out.

best length suppressed and not suppressed? 8.5 9 ?

Not necessarily looking for that, but I understand it's easier to do than other calibers should I want to.

I have one 100 yards and under great gun. Over that I don't care for it. Just my opinion

somewhere around 8"-11" is the optimum barrel length for 300 blk out. Varies with ammo
To OP if you don't plan to suppress the 300 blk out it isn't as appealing. Maybe look into the 6.5.

I don't have extensive knowledge but from what I gather if your going to shoot supersonic 300 blk you might as well pick another caliber. I wouldn't shoot subsonic 200 yards. That doesn't seem ethical. OF course you could switch back and forth when shooting longer distance but then your going to need to keep adjusting your scope.

What's the ethical distance for deer with subsonic with a can? In Florida it's now legal to use cans, I may have to look into this now. It's funny I never considered the having to switch scopes things but that's definitely true. You could go with one of the red dot/ scope combos. Scope for super and red dot for subs?
The other benefit is same mags as 556 and same everything but barrel right?

I don't have one and haven't really studied the cartridge much. I have a buddy who builds AR's and is what I would call and expert. His favorite is his suppressed 300 blk but he doesn't take it when hunting past 100 yards. Again I'm not too familiar with the cartridge but it was intended to be suppressed with subsonic and shot at short distances. I'm only repeating what I've been told. You could get a scope with tactical turrets and write down to quickly go between the two. It's a great round for its intended purpose but I would go with the Grendel if this will be its most common use.
Not sure about the mags but it does have a different barrel and bolt (I think)

Yes mags and bolt are interchangeable between 300 blk out and .223/5.56. Barrel is the only thing you have to change

I think LSUFreak was talking about the 6.5 which does have to have a different bolt as well.
LSU_smash, why don't you like it over 100? Just wondering.
Posted on 12/14/16 at 11:21 am to ducksnbass
No I was talking about the 300 blk. I put (I think) by the bolt because I seemed to remember it was different but I would go with civiltiger on that one. I have looked at the 6.5 and will be my next build I sometimes forget what interchanges with different calibers. That's why I let my friend build mine. I just pay him the money.

And the gas tube, correct?
Posted on 12/14/16 at 11:50 am to RATeamWannabe
You can use the same gas tube on and 223 and 300 blk out as long as they have the same length system (carbine vs mid vs rifle).

Need pistol length gas tube for 300BO.
Mid length won't cycle them, and carbines are kinda iffy.

Ah, my bad.
So, what I'm hearing is, 300blk would be good if I ever plan on running it suppressed? (valid possibility if the NFA law passes)
Otherwise, look at something else?

Yes, I have shot them suppressed and its ridiculously quiet when shot with subsonic. My next build as of now is a 6.5 but if the law changes it will be a 300 blk. It is awesome suppressed if your not suppressing it then it's nothing special.

rule of thumb for 300 Blackout guns. If your gun has a 16-inch barrel, a carbine length gas system should work just fine with supersonic and subsonic loads – especially if you use a silencer. It’s not a hard and fast rule. Some rifle makers, like Noveske, use pistol length gas systems in their 16-inch barrels, which other makes use carbine length. If you are going to buy or build a short length barrel gun, less than 16 inches, do yourself a favor and choose a pistol length gas system.

You can kill a deer with 300bo subs. I know people who have done and continue to do it. Personally I don't consider it ethical at any distance. Guy I know who does it likes it because it doesn't tear up any meat. It basically makes a .3" diameter hole through the animal so bullet placement is more important.
