Hello.

Does anyone have any real data. Is there a big difference between dbs? What about subsonic loads? All input appreciated!

No one answer... You have to account for barrel length, subsonic or not, bullet type, suppressor maker / design, etc, etc. I think you're going to have a difficult time getting a true apples:apples comparison here.

The .223 and .308 both suppress about the same with SRT suppressors (Hurricane .223 and Shadow .308)--the SPL is dropped to around 132-133 dB with full-power ammo.

Bullet flight noise is directly related to projectile diameter. So even if you could get the same muzzle signature, the .308 would be a bit louder.

hcook,

That's pretty obvious.

Thanks for the input. The reason for this was one friend of mine who insisted on getting a .223 rifle instead of .308 because of the smaller caliber and therefore less audible report...I did say to him that I have been unable to identify .223 rifles from .308 rifles at the range...by the sound that is. I guess .308 is still a bit louder.

.308 suppressors are much larger and more cumbersome compared to .223 caliber suppressors. If both rifles had the same size suppressor the .308 would be much louder.

I'm sure that you meant .223/5.56.
