This.The 22 mag generally breaks the sound barrier.
And this.a gun always sounds louder when somebody ELSE is shooting it.
Not really. It shares more in common with magnum revolver cartridges than rifle cartridges and behaves much the same.22 WMR is a rifle round
it isn't that loud at all in a rifle when most of the powder is burned up in the barrel. I had a S & W M-651 with a 4 inch barrel and it was very loud with a lot of muzzle flash
The .22Mag is loud not because it goes supersonic but because it's loaded with a lot of slower burning powder (magnum revolver burn rates) relative to its bore size. Which means a lot of expanding gases through a small hole.
Don't know why that would make the .22 Mag seem louder than larger calibers like 9mm that have both more case volume and greater chamber pressures.
silencers are not made for revolvers because they cannot silence the supersonic gases exiting the barrel/cylinder gap.
fyi,
Not in my experience, especially for an auto like the Automag II.As stated previously as compared to a 357mag the 22mag is closer to a mouse fart in its report.
