Shhhhhhhhhhhhh! - Part 2

I tested my fancy    sound reduction device   with a .410.  The only sound was the pressure released as it popped the barrel back out of the shooting hole.  It was like popping a chuck off of an air hose but not as loud.   It's only good for working up loads for pressure.  There's no way to use it when shooting for velocity or accuracy because the bullet goes directly into the ground but it definitely works for its intended purpose.  It should help cut down on the amount of loading that I have to do at the range.
