View Full Version : 300 Blackout Loads
I'm starting to reload 300-BLK, any of you guys working up loads for this cartouche?
Been doing 300 BLK for 10+ years...what you looking for?

I’ve got 1,000 Speer 125 grain TNT bullets I need a good supersonic load for.

AA1680 is an excellent choice.
What powders do you have available?

Hopefully you can open the link I pasted. A lot of load data - Work up carefully and use at your own risk. I have tried the Nosler 110 grain Varmagedon loads and my results were the same as the authors.

I forgot to add that those are Nosler Blems bought from Shooters Pro Shop and clocked a little over 2400 fps using a Magneto Speed V2.

I’ve got H110, 296 and 2400. Thanks for the spreadsheet.
I'm looking to load subs, but I'm also interested in everyone's pet loads.

I am going to dust off this topic and ask about powders that are used for the 300 blackout loads - going with both sides of the story for heavy and slow and light and fast. Also any recommended bullets that seem to perform well.
I have the brass, primers, and some misc bullets that might be useful...I have one NOE mold for a heavy weight at over 240 grains. The heavy weight bullet will be used a single shot T/C Encore.
Rifle barrel(s) are 2 @ 16" with 1/8 twist.
Real use will be for punching holes in paper at short(er) ranges. (Sub 100 yards)
I figured I use the info about powders / bullet weights to start researching on what new (updated) re-loading books I will have to get.
[added/adding]
I have both a progressive and a single stage press to work up the loads.

I’ve had good luck with W296 and Speer 125 TNT bullets for supersonic loads.

Resurrecting this thread to get some info:
I have a can in jail that will primarily live on a AR pistol.
I got me a 300 blk barrel but I have not installed it yet since there is no ammo to be had and reloading components are also scarce.
So, this is what I have:
small rifle primers (some)
H1000
Varget (This is what I have most of, as far as powders)
700X
Assuming that I can find some 30 cal bullets at a decent price, is there any load that will work with what I have on hand?
Both supers and subs, even though it will be a while before I get my can (hopefully by then I'll be able to find a better choice in powders).
I am itching to get this project going, but without ammo I would just turn a wotking, proven firearm into a paperweight...
I use AA1680 as mentioned earlier, would recommend.

I don?t think you will be able to use those powders. Most published loads use the magnum pistol type powders.

Post in the wanted. I?m sure someone would go for a trade as varget is always in demand.

I thought I had responded to this, but I must have not finished.
Text me later. I'm pretty sure we can work something out.
