How did different ammunition types perform in the 300 Blackout Mini SPR?

What are the advantages of using a muzzle brake with a suppressor on a 300 Blackout rifle?

Muzzle brakes can act as superficial baffles, potentially reducing suppressor noise slightly and, more importantly, significantly decreasing carbon lock, making suppressor removal easier, especially with gassy rounds like 300 Blackout.
