I know that a shot fired from a short barrel will sound louder to the shooter than one fired from a long barrel. Will the report sound louder to something downrange as well?
Synopsis: I want to set up a bolt-action .22LR for suppressed shooting (with subsonic ammunition). The current barrel on one candidate (CZ 452) is 22.5" long; if I get the barrel cut, threaded, and crowned at 19", will it change the loudness of the downrange report versus a 20", 21", or 22" barrel?
There are many discussions about "optimal barrel length" with regard to velocity and accuracy, but none about report.

Re: Barrel length's effect on muzzle report
I'll be entirely honest, I have two Savage Mk2 bolt action 22's.
The FVSR has a 16" barrel. The old MK2 has a 20 inch barrel.
I cannot tell that either is more or less quiet than the other.

I don't care what your chart says
Re: Barrel length's effect on muzzle report
Same ammo, same suppressor, same host but a barrel difference of 3" what he said. You probably won't be able to hear the difference until you get the barrel under 12"

Re: Barrel length's effect on muzzle report
I am inquiring about the report heard at the target, not the shooter.

Re: Barrel length's effect on muzzle report
Theoretically, the long barrel would likely be a little more quiet.
Whether it is enough for the db meter to tell a meaningful difference 50 yards or more away...

Re: Barrel length's effect on muzzle report
19" vs 22" will be a very small difference. 22 vs 5, will be a big difference

Re: Barrel length's effect on muzzle report
Same answer. If you start with a louder sound it will stay louder but if you can't really tell the difference at 1 meter you won't really be able to tell the difference at 100 or 1000 meters.mbogo wrote:I am inquiring about the report heard at the target, not the shooter.

The intensity of the report will decrease over distance.
Go to this link.

Scroll down and enter the data then press calculate.
Let's say there is a 3dB difference between the rifle and the pistol, here is an example of the change between two different blast intensities at 100 meters vs 1 meter.
