300 Black Out in subsonic reloading

[tbeak]

does anyone reload this? i have a guy at work that wants to start reloading this round and he asked for some data on it. said he is getting a bolt action rifle in this round. he intends to hog hunt with it. any help is appreciated.
Thanks

Not in subsonic yet. A friend of mine just loaded me up 1000 rounds.

The 300 blackout forum has the official recipe but it's basically about 10.5 - 11.0 grains of A1680 pushing a 220 SMK.

I can't access the site at work but that's pretty close to the load. I'm waiting on my 300 upper but already putting together the components.
