300 blackout reloading

Post by chrpw7 on Thu Mar 21, 2013 6:19 pm

Beginning reloading this weekend. Intend to start developing 150 gr ballistic tip, 180 gr soft point and 190 smk moly coated. Mainly for deer/hog hunting.
Major problems finding components. Finally cobbled together all the equipment. But powder and PRIMERS have been a b*&%-. Got primers lined up, finally ttl.
So now, powder. All i could find locally was sr4759 and i cant find any blackout loads online for this. Everybody on the forums says buy a few manuals. Headed to barnes and nobles saturday. But in the mean time, anybody got any experience or suggestions for sr4759 and blackout with mid range bullets. Dont like the idea of working up from squib loads.
Considered referencing a burn rate chart to find something similar, cross reference recipe for blackout, reduce load, and try. Uncomfortable with all these variables and different powder pressure curves, load densities, etc.
Any help would be greatly appreciated. U guys rock.

I'm interested in this as well. Just a note I looked at every manual out there and didn't see 300BLK in any of them. 5.7X28 either (expected that).

Was about to post this very question. I'd love to get my hands on some H110 or W296. CCI small rifle #400 primers should be in stock at midway in a few weeks.

If anyone has any leads, let me know!

Cross reference the burn rate chart might be your best bet. Find the closest powder to SR4759 that manuals list 300BLK loads for.

I am looking at a burn rate chart published by Hodgdon and SR4759 falls between H110 (faster) and AA1680 (slower). Both of these are good 300BLK powders. Since the unit wt. to energy ratio varies some by powder type, I would use H110 load data and start at the low end for the bullet weights you plan to use.

Load 5-10 rounds and test for cycling and pressure signs.............................

Thanks for the replies. Guess its not just me. No data in any manuals? Certainly leaves me feeling on my own.
I couldn't find h110, aa1680, accurate 5744 and 4100, ramshot enforcer, or a couple others i've found data for.
Also, no one is loading mid-weight bullets (150-190gr). These were all i could find in bulk and figured i should get what i could while i could. Hoping to make functional subsonic loads with these after developing accurate supers.
Seems i'll probably be on my own with these loads. I'll be sure to post updates as things develope.

Go to a 300BLK website/forum and look at load data for the bullet weights you have. Might not find the exact bullet weight loads, but you can work with "close"........

Hornady is your friend. Hornady 9th edition has a good section for 300 AAC/Blackout.

There are a few things to consider when loading the blackout and what loads to use. I may have missed it in your post but whether you are loading for the AR platform or bolt action makes a big difference in your loads.

Just noticed this in your post. Don't wast your time. Barnes and Noble doesn't sell reloading manuals. You best bet is a reloading supply store or order it from Midway.

I don't see an data for SR 4759 even on Hodgdon's Web site. The fact that I can't find any data for it suggests that it might not be a good idea to use that powder. I hesitate to say much because I'm not really up to speed on all the interesting things that people are doing with the subsonic loads in the 300 BLK, but I have to ask: Where did you get the information to decide to use this powder for that caliber? I saw online where one or two people had used it, but it seems like there are much better choices available.

hey guys... listen. i aint trying to be no hard ass. but
dont reload a damn thing untill you read and understand what yoiur doing. go to a gun shop, if your in jackson go to vans and buy a lyman 49th edition manual. reloading is dangerious
take it from me. when i started reloading. i pulled the bullets out of 9mm,357, 38 sp and 300mag. mixed it all to gather and reloaded
damn near blew my gun up....read...read...read...ask questions
rewd.. some more. this stuff is dangerious. and there are more things to concider than just dumping powder into a shell
the cases have to trimmed and cleaned, or you may have head space problems..
read....study....

You're right about everything you said, but Lyman 49 won't help. No 300 Baclout data. Te only manual I've seen that has it in it is Hornady 9th, though I don't have the new Nosler 7th edition to check.

But you're right -- I wouldn't do anything until I had seen the data in black and white in a reputable manual... Especially if it's a new caliber I wasn't familiar with and ESPECIALLY x2 if I was new to reloading. I had a friend that has a major scar on his cheek because he thought he could get away with substituting W296 for W231 if he dropped the charge down a bit.

I've been monkeying with the 300 blk out for a few months. So has Miker84. I don't think either one of us has used midrange bullets. I know I haven't. Most people are either one extreme or the other. Really light bullets or 200+ grainers. I am using the 208amax over 10.2 gr of A1680 in my AR to get 1000fps. In my Remington 700 I have dropped to 9.6 and am still transonic bouncing around 1050 to 1100. Another friend uses Lilgun. I don't know his powder load but I think he may be using 175gr bullets I'll track him down today and find out.

As for finding components. Van's has the 208. I chose this for hogs hoping with the plastic tip it might at least deform a little when it hits a hog. You can find them online at huntersdiscount I think. I can't find the bookmark right now but it is in Alabama it may be hunterswharehouse. I ordered 500 of them and they said out until november 2013. I got them about 6 weeks after I ordered them so sometime in febuary.

I'm loading for an AR, not bolt just for clarification.

I do shoot some 147gr for supersonic plinkers. They'll ring steel and hit paper but I wouldn't hunt with it. I'll probably not load any more of these once I burn up what I have.

Like Q says, I REALLY like the 110-125 Barnes for supersonic.The 110 Tac-TX expands all the way down to 1300fps and it gets to the 2300fps range in a 16" barrel using H110.

I prefer the 208-220 for subsonic, but also have a 178 working subsonic, but not very accurate.

Miker have you tried the really really heavy bullets yet? Like the 240gr berger. I have tried 225 and it stabilizes fine in my 1/8 twist AR. I'm sure my 1/7 twist remy will handle the 240.

I haven't touched supersonic anything. How much H110 are you using?

Haven't tried any of the 220+ stuff yet.

warning: this is my load so it may not work in your gun, etc,etc always consult a manual first and start at the minimum.

For the 110gr Barnes Tac-TX or Hornady Vmax 110gr I use 18-20gr. 18 will get you to 2200fps. 20gr will get you to 2400fps, but you'd better use good brass. I've popped a couple of primers and had hard extractor marks at the 20gr level with some brass. The Remington 300 brass hasn't shown any pressure signs at the top end. I stay right at the 19gr range and haven't had any issues with formed LC brass or Remington.

Lots of questions and good advice.
First, reloading strictly for ar platform. Limits my oal to magazine length and length to ogive is also a consieration for proper feeding.
As far as why i chose this powder: i couldn't find any of the popular or common powders locally. Consulted a few burn rate charts and found sr4759 to have similar burn rate to several of the common blackout powders (enforcer, lilgun, and a-4100). Slightly faster than h110 and even a little faster than a-1680. Also available locally. So thats what i bought. Still might not be the best choice, but it was the best one i had. And thanks for the heads up about barnes and nobles. I'll check the lgs. Dont want to spend on something that wont help tho.
I understand the the safety concerns with reloading. I mean every properly loaded cartridge is basically a precision engineered BOMB. I will certainly excercise all due diligence and caution.
