So I have been working on reloading 300 blackout. I have come up with a very cheap plinking load that is subsonic, very quite and is fun to shoot. I bought brass from 300blackoutbrass.com. I have no affiliation with them and just happened upon them. I must say though this is some of the best converted black out brass I have used. The overall length varies slightly which can mess with your crimp consistency thus giving you vertical spread but again this is my plinking load. I am using palmetto projectiles, again no affiliation. These projos are awesome they are lead which makes them cheap BUT they are coated so they will not clog up your silencer or your gun. I am using accurate 1680 which is a little dirty but not awful. Mostly just residue in the lower that I can blow out with shop air when cleaning my gun. I am using this load on a 8.5 inch barrel with a average velocity of 1010 fps with a deviation so small I never have gotten one to go supersonic or even transonic. Very good for slamming steel plates suppressed so you can hear the ting or steal, all great for putting smiles on faces : ). I am loading this round for less than .35 a round brass included so once I start reusing the brass it will be about half that. So I am shooting subsonic blackout as cheap or cheaper than 5.56 I could'nt be happier. If any one would like this pet load pm me and I will divulge it. Took a lot of work and research but I have a winner here. I am so pleased with my hard work. Bolt holds open every time and it is consistent. The only downside so far is it being a lead projo you have to flare the case which means an extra step which slows you down. Obviously this is a pet load for my rifle but anyone could do the same. Can finally afford to really shoot this thing a lot now. Pictures to follow.

Well it will not let me upload a pic says file is to large. It is a cell phone pic not sure what the problem is. Will try again later.

Seems a lot of folks say 300 blackout is going the same way as the 6.5 Grendel away after a few yrs of Hoopla!

It may go away, and I can understand why it may but I am keeping mine. I eventually plan on building a 338 spectre. 30 percent more knock down than a 300 when shooting sub or super and is only a little more expensive to shoot. Honestly subsonic black is not a whole lot better than subsonic 9mm. Basically when shooting at subsonic levels the only thing you can do to make it have more energy is a heavier bullet. Remember ft lbs of energy when calculated fps counts twice, bullet weigh only once. Thus if you are stuck at 1050 fps the heavier the bullet the better.

Wasn't trying to start anything but simply wanted to make sure u knew!

I still remember all the HOOPLA about the Grendel for several yrs. many saying military might eventually use it and all the Grendel Stuff but now it is basically gone!

I do wish u all the best and enjoy!

I suggest a case gauge like this when reloading 300. still trying to get the pic of the loaded bullet to upload.....

If you want some super quiet sub loads for a bolt action try some VV n32c tin star powder.... you will be amazed at velocity spread as well as noise.

If I had a reloading setup id keep my blackout. Got tired of paying 1$ a round for 208amax subs

I am having trouble sending PMs but I would like to see your load data. Thanks sld.

I'm interested in your load data as I just bought some if that powder for blk out. Thnx

Pm`s sent, work up to it and be careful. Mileage may vary.

Also someone said something about the 208 hornady. That's all I use to shoot and I agree it's good ammo but high. You can reload that round for less than .50 per. So if toe going to be in the 300 game I suggest reloading

This load is working so well I went today and picked up another 1k projectiles and 1k pieces of brass
