I have to say this has made me take a second look. I have to wonder if he is downplaying the trajectory issue.

Finally something worthy to accompany my .356 TSW pistols!

I enjoyed that and agreed with Hailey's conclusions.

I've shot 12" steel plates at 400 yards with my 8" blackout without any issues, I'll have to give 750 yards a try next time!

I have a boner for an 11.5" .300BLK barrel for my ACR. Some people here have an outright disgust for the .300BLK caliber and will post inflammatory shit. We're talking about a freaking caliber of a bullet.

I would have to guess that the 750m shots were made shooting 125 grain supersonic or similar. Can't imagine any subs reaching out that far.

Interesting round. I'd jump on it if it were more affordable, even though most of the benefits might be wasted on us in CA.

I've got an 11.3"

Gonna cast some 247 grainers here before too long. I'll post results. No, I don't have a suppressor for it yet.


But... cost per ammo projection:

5 cents per bullet at 1.50 per pound of lead, 7k gr in a pound, 247 gr per bullet.

about 3 to 3.5 cents per case (I make my own)

3 cents per primer

2.8 cents for powder at 11 grains. call it 3 cents.

14 cents per round for the first round. 9 cents per reload after that until the case splits.

Dunno what F_M is going to charge for his heavy jacketed bullets, but I'll be getting at least a few of those for special occaisions.

eta: Since we're talking about suppressors now. What do ya'll think of the liberty Mystic? I was thinking about getting that for both my 300 BLK ar15 and my M11/9 and just swapping it back and forth.
Link Posted: 11/13/2012 7:26:47 AM EST
How hard is it to find ammo for that rifle? Looks like it costs as much as .308.

I shoot 600yd in High Power, and that's fucking tough. And I have a 20" barrel with really good irons to do that with, and it's a much larger target than that 19" silhouette.



So, after watching that, I'm thinking...

I have a SF 762k suppressor.
I have an SBR AR.

Would I be foolish NOT to build a 300BLK upper with one of the 8.2" Noveske barrels?

Not hard at all. Factory ammo is still a bit expensive, but very available.

Great candidate for loading your own. Tons of people make the brass (ahem, Including myself) from 5.56 so that component isn't hard to find.

Hopefully, you'll have already stocked up on powder and primers. The panic buying will probably be putting a hurt on the stockpile of those soon, if it hasn't already.

Like most new things if you just look at the math, its a capable round with little change to standard parts. All other the AR variants require different mags to do better. I like the 300 blk just for common parts and materials. Extremely impressed with the 750m shot. Now get it into a Long piston gun that doesn't need a floating carrier and buffer tube. That will get me 100% in (anybody want to tackle a Sig 556 patrol rebarrel into 300 blk?)
Link Posted: 11/13/2012 7:35:30 AM EST
I've been considering making a .300BLK "hobby gun" since I already have a SBR and a .30 cal can. This might push me over the top.

I wouldn't buy one unless you reload, it's available but a lot more expensive than 5.56x45.


That said, I got another lower I panic bought on the 8th, and now that I got a press, .300 BLK could rationalize some more panic buy lowers.

Travis can do it. This piece is far more fair and accurate than other recent "expert opinions" on the topic. Par for the course from Travis.

Differing length of gas tube that accompanies the new barrel.

The hobby gun comment (to me) says buy a complete upper from a Manf. as you can run into tolerance stacking issues if you grab parts from 10a different places. Look at the .308 market as an example of non standardized. That being said, the AR market is super standardized so I'm not following his logic train on how he got there.

Anybody got an ITP from AAC they want to share?

buy lots of AA1680! and small rifle primers! very easy to reload, most powders that work in the 44 mag transition over to the BLK wonderfully.

God I wish Dave would hurry the hell up with my die set!

Andy, no issues with fouling the barrel with cast bullets? Is that because you are running subsonics?

I have a 16 inch AAC .300 upper, can't ave SBR in NY, and I've primarily run 147 grain out of it.

Looks like our very own bigbore was way ahead of the game we he suggested such a while ago....(off to search the archives). I do remember that the 300/221 fireball/whisper was the flavor at the time.

ETA: I keep getting an error message when I try to search....

I distinctly remember a build he did with a short .300 barrel with a can and he labeled it the "perfect" home defense gun.

Yeah, I'm firmly into the "if money weren't an issue..." stage now.

It'd cost me maybe $600-700 for a really good upper, $130 for another adapter/brake for my SF can, plus $50 for a set of reloading dies. I have all the assembly tools and everything else.

If I went cheap, I could probably get it done for less than half that.
Link Posted: 11/13/2012 8:02:15 AM EST
It would have been great if he'd mentioned what bullet weights he was referring to. My guess is 110gr for that kind of trajectory.

I would LOVE to build a .300blk. Hobby schnobby, I'd do it. I think the round itself is genius at work. Someday.

Also the terminal ballistics would be very interesting to hear more on as well.

Can't say, personally. Haven't actually cast any and fired them yet. I've got everything but the actual lead. Need to see if I can hit up some tire shops in town for wheel weights.

But from what I hear on the cast boolits forum, leading isn't too bad of a problem with sub sonics.

last batch I ran straight lead. after about 9 mags of rapid fire I had some leading. Ill just up the linotype content and should be much better on the next batch.

Thought that I heard in another 300blk thread that the different manufacturers determined a piston system would not be better for this particular cartridge....
