Thread: 300 Blackout Super sonic loads

I shoot both cals, both suppressed, both sub and super.

The 308 rifle has a bigger suppressor than the Black out.
It’s an old school DPT that is about 400mm long.
The Black out has a DPT mini on it and a 4-1/2inch shorter barrel.

I find that the .308 is quieter with both types of ammunition unless both rifles are un suppressed. Then the .308 is louder with full power loads but not fundamentally louder.
It’s not like the difference between a .22 and a .223
You have to be familiar with both or hear them in quick succession to know which one is being fired.


As I write, I realise all of the above is a long way of saying the suppressor makes more difference than the difference in caliber in this scenario.
