.30 caliber (specifically .300 AAC blackout)
1 in 8 twist
Threaded for AR-15 flash hiders and suppressors
Fits Savage Model 10 short action
Anyone know where I can find this?
Also, can I use my Stevens 200 (Savage Model 10) .223 bolt assembly and receiver for the .300 AAC blackout?

You can't. The threading is the issue. Standard AR-15 threading is for a .224 bore and uses a 1/2" major diameter. Bore that barrel out to a .308 bore and the barrel is too thin at the threading. For that reason standard threads for a .30 cal bore uses a 5/8" major diameter. If you don't mind an AR-15 muzzle device, barrels like you're looking for should become somewhat readily available soon.
The other problem that you will likely run into is that the normal Savage .378" bolt won't reliably eject the short cases. People have been battling this issue trying to get a .221 or .17 Fireball to work in the action for some time now with little to no success. Savage appears to have solved the problem themselves as they have announced a .300 BLK rifle for 2012. The Savage factory rifle meets your needs with the exception of a 20" barrel and the larger sized threads.

I mean ar15 muzzle devices designed for the .300 BLK cartridge, so those should work on the new savage which I'll probably pick up.

There you go. Don't think that they've hit the shelves yet, but I can't say for certain.
You are not going to find any 18 inch 300 BLK barrels - 16 inch is SAAMI standard length and people prefer the shortest legal length as 300 BLK works well in shorter barrels. Also, subsonic ammo has a higher chance of going supersonic in an 18 inch barrel.
