Most centerfire rifle ammo is supersonic, considering Mach is only ~1100 ft/s at sea level. That doesn't mean you can't suppress the caliber.

If you load full speed ammo, it'll be quieter than unsuppressed, but you'll still have the Mach crack. You can also download heavyweight bullets in the subsonic range.

Any .308 suppressor will work for you with .243, provided you have the right muzzle threads. A specialty .243 suppressor would work better, but 6.8 guys are using .308 cans on their 6.8/.277 barrels with good results.
