Only subsonic rounds lend themselves to being silent. This round is travelling at around 3,000 feet per second. It's probably the 55 grain variety, but it may be the 70 grain weight. Still it's going to make a lot of noice.

Still it's going to make a lot of noise. It is possible to completely silence the sound of the cartridge from a much higher-powered cartridge.
What cannot be silenced is the sound of a bullet breaking the sound barrier. But, that sound is not very loud, about like a child's cap pistol. A firecracker is very much louder.
