Some could tell me a table or something similar with the sound in db that produce each caliber. I know that depends on some other factors like barrel, powder, break or others but some aprox.
Thank you.
Thank you.

Re: Calibers sound
As many would tell you here, testing dBs is a dicey process. There are few equipment/weapon/cartridge standards. Given that, here is a rough guide to begin with. Only one weapon had a brake (see below), a brake would add considerably to the preceived and actual noise at operator.
Note : 164.5 dB approaches the practical limit of impulse noise measurement capability inherent in most modern sound level meters.

.410 Bore 28" barrel 150dB
26" barrel 150.25dB
18 _" barrel 156.30dB

22" barrel 154.75dB
