How to make 300 Black Out Brass

question for you guys shooting the 300AAC- what's the lightest weight bullet that will stay subsonic but still cycle the action reliably? I know the 220+ bullets will do it, just wondering if 200's or even 180's will still work?

saw some of the guys are casting 220+ grain bullets and using them for subsonics. makes sense I guess!
 
I haven't loaded any subsonics yet but here is a good website.

http://www.300BlkTalk.com/

It has a lot of info on the round as well as a bunch of loads people have been using.
I think the forum is a spin off of Silencer Talk and is run by Rsilvers of AAC.
 
what barrels or uppers are you guys running that have 300's? I may be in the market for a barrel in the near future.... does anyone know if anyone local/atlanta area have just barrels in stock in 300AAC?

I've looked at Noveske, Wilson Combat, and I think Delta Arms is also making them. Not sure if AAC is making just the barrels. i'll have to send it out to get it converted to work with my upper but just looking to get a price idea of barrels... and what is working for folks (gas tube length, twist, etc.). Probably will be 16" to start with. :)
