I am looking to get a .308 that i can shoot subsonic. I see several different possibilities. Is there one that will work as a standard as well as subsonic or is it best to stick specifically to one use. I know the ballistics have to be spread between sonic and subsonic

To shoot both you will want a bolt action (or is that what you are thinking anyways?).

I don't know that one brand is better than any other besides preference and options. I like Savage myself but every brand has it's fans.

I am a CZ fan and it probably will be a bolt gun looked at a savage yesterday and I was impressed with the way the trigger broke. I started this off with 308. But would the 300 blk round be better for a dedicated system. I reload but I understand it can be difficult to reload subsonics in the bigger case shells due to flash over.

I am not very familiar with the 300 Blackout but I believe the supersonic rounds are very anemic. It just doesn't have the case capacity for any real power.

I would go with the .308 personally if you wanted a serious long range round. I haven't experimented much with subsonic rounds yet but I believe good info is available.

The ballistic performance of all subsonic rounds is very close. It is simple a matter of velocity and ballistic coefficient. The .308, .223, .300blk, and even 9mm will be fairly equal. A .45 is usually all little slower and does not carry the same range. At a hundred yards they would be very equal ballistically, except the energy. Personally I prefer a 9mm for subsonic applications since it can be fired from a pistol or carbine. The 9mm 147g projectile is sufficient for any application, and it is far more inexpensive and readily available.
There is no doubt that a full power .308 is an excellent round, but reliably finding and firing the subsonic version requires additional constraints. A bolt action is probably the best solution. Some firearms like the FAL can turn off the gas system easlily, making it a single shot rifle that must be manually cycled. Yet a twist of the gas regulator makes it feed standard .308 normally.

If the bullet is going subsonic (950 fps or so), and it's the same diameter, and the same bullet, it makes no difference if it came from a 7.2x39, a .308, or 300BLK, etc.

SC-Texas is right on.

Charlie, in a ballistic sense you are right, but the 300 Blk was designed to do this. The 762x51 wasn't and has issues throwing that bucket at those velocities.

I'm agreeing with you. I think.
