Testing subsonic with a brake.

[RotARy15]

I understand testing subsonic loads without a can because of possible strikes. However, does this apply to muzzle brakes as well?

I plan on building a sub load and am curious as to the potential hazard.

Better safe than sorry is probably the best answer

I don't see a reason for concerne myself, It's not going to extend far enough past the barrel to be in the way and the tollerances' are alot more than with a suppressor.

Why not develop the load with the sound mod on! If it is going to strike it, it will do regardless of if the load is developed or not. So long as you trust the thread is concentric with the bore.

Make a visual check from the Reciever end looking through the barrel with the mod on, if you see a half moon shape it will strike, if you see a round hole chanes are it won't strike.

Hope this helps Pete.

This is NOT sound advice (pun intended).

The purpose of testing a subsonic load WITHOUT an expensive suppressor attached (or a muzzle brake) is to determine if the bullet is properly stabilized so as to prevent tumbling/keyholing and...therefore...baffle strikes. Whether the threads are concentric to the bore and the suppressor (moderator) installed properly is always a good idea, but just because they are ok, does not mean that ammo can't still create further problems if the bullet is not properly stabilized as it exits the barrel/enters the brake/suppressor.

In terms of removal of the muzzle brake...I generally do when initially testing unless it is permanently attached to the rifle in such a manner as to prevent removal.

This is correct
