300 blackout cast load data

[thumbs]

Can anyone send me in the right direction to get some load information for loading cast bullets for the 300 blackout?
I will be loading powder coated 155gr bullets. I have looking in my four load books and on the Hodgdon reloading site but can't find anything for cast. I looked in the Lyman Cast load book but it doesn't show anything for the 300 blk.
Not necessarily asking for load data but where can I find it? I can find plenty for jacketed bullets but not for cast.

thanks for the help

[Conditor22]

type "300 blackout cast load data" into the search box on the top right of the page

[Texas by God]

Starting loads for 150 gr jacketed will be fine for your 155 pc boolits. About 17-1800 FPS. That’s what I did. My 7.62x39 with its 1-10” twist shoots better than my .300BO with its 1-7” twist but YMMV. AA1680 or H110/W296 are good powders.

[thumbs]

Thanks guys Good info straight to the point no **. Doesn't happen often. I appreciate it. I have W296. I heard somewhere that 4227 was good but never got any numbers. Did you size your 300BO to .309?

Thanks I type it in and see what I get.

[Lloyd Smale]

I size my bo to 309 casted out of a hard alloy (probably 20+) and use a gas check. Best powder for me so far is 110 but wc 297 and wc820 and 4227 have all worked well. My buddy uses nothing but 1680 but about half of his are subsonic and I don't fool with subsonic. cant give you data though because I found the rcbs 130 spitzer gas check and haven't looked back.

I do not have cast data, but this publushed data should get you started.
I use 1680

Using the Lee 155gr 312 bullet, 15gr of IMR4227 works really well for me in my RAR 300blk.

[Lloyd Smale]

do you have a link to that data. Its one of the only ones ive seen that uses aa9 and ive been experimenting with it myself but with 130 grain bullets. Id be interested to see the article.
I do not have cast data, but this publushed data should get you started.
I use 1680

It was on Load Data so I cannot provide a useable link.
The data is, obviously, from Handloader magazine.
I stopped subscribing a few years ago and just do Load Data
Brian Pearce is a sane man and my favorite gun rag author
Just as a test, I will do
Just for fun of it I will look for AA9 data in the 130 range and AA9 data in general
It is an underappreciated powder

[jmort]

Here is a start
I included other data for those who have some of the other powders
Should be useful data for load work-up

There is more, but I do not want to further clog- up the thread
I can put up specific requests
Clearly, you have to do your load work-up
Safe and sane
Start low
If you have never done load work-ups, be careful
This is not directed at Lloyd or anyone specifically who is experienced and knows what they are doing
Just saying, be freaking careful
The Accurate data is from Accurate but that don't mean it's accurate
Hope this helps

[jmort]

BTW, just one more thing I like about the 300 BO
Plays wells with pistol powders in an AR which can be a problem cycling

P.S. I was just studying the AA9 data for 300 BO
As a general matter it is really interesting in this application
Looking at the 220 grain data, I am impressed
Thinking 8 more pounds is in order
I know it works real good in my handguns

[Lloyd Smale]

ive been shooting the 130 rcbs spitzer gas check with 15 grains of wc820 (aa9) and am getting inch groups at 50 yards and at a 100 about 2 1/8. Id does a bit better with wc297 and even better yet with 110 but I have 6 kegs of 820 so from here on out it will probably be the powder I use. Maybe when I have time ill fool around with different primers charge weights seating dept ect and see if I can do better but bottom line is even 3 inch at a 100 is plenty good for pounding steel out to 200 yards and that's what I do with them 90 percent of the time. For hunting its the 110 barnes all the way. My 16 inch gun shoots ballistic tips and sst's great but 110 barnes x bullets so well im almost embarrassed to talk group sizes because some would call me a liar. Ill put it this way the 8.5 inch 300 puts that bullet into a 1 1/8 at a 100 yards YAWN! The 16 inch gun is probably the most accurate rifle ive ever owned other then dedicated heavy barreled 22 cal varmint guns and it would give most of them a good run for there money.
