Anyone ever try to see if there is ever any velocity difference between a barrel with a MSTN type brake vs. no brake?
I figure if a suppressor increases pressures that increase the MV, so if gas vents out i figure you may have a slight variation vs. standard A2 hider?
I know with my bolt action I have 2 zeros, one with a brake and another without.
Well...i finally went out and shot my SPR with an A2FS and compared it to a MSTN break.
Accuracy was about the same, more or less...but when I switched to the MSTN from the standard flash suppressor, I was about a inch to 1.5" higher with the MSTN break...
Whats that mean? higher velocity, barrel harmonics...????any ideas?
