Can someone loan me a digital sound level meter?

FWIW, unless you are using sub-sonic rounds you will probably not get very relevant supressor data because the sound meter will pick up the round's sonic crack each time.

Ask me how I know?

However, the sound pressure level ( of the muzzle blast ) can be suppressed to under the bullet flight noise level, when measured from the 1 m to the side location as per the MIL STD 1474D.

Of course in the front sector the suppressor will not have an effect purely based on dBs..

Guys - awesome suggestions *but* I just want to collect some basic data.

I highly doubt there is good data on 12.5" Kalashnikov guns, otherwise I wouldn't be interested in trying to do this.
