did a few quick tests
in the basic set up.. 5.45 & tok sound just like a unsupressed 22lr. :P
7.62x39 is pretty close as well..
didnt get to test it on the 9mm as its coming down in buckets here..
all in all its just like we said: noise reduction for shooting with no earpons... but not silent
this is a 9mm registered can that im running 7.62x39 thru for this test...
sure it could have been a little quieter if it was 7.62 hole size instead of 9mm...
but the entire idea for this build is to be able to use it on different stuff.
as you can tell this is very hearing safe.
factory 7.62x39 wolf steel case ammo on all 4 shots.
with just a little tweaking im sure this would be even quieter.. but im a rookie at this part of our hobby.
