Once upon a time having a suppressor in England was looked at with askance by the authorities and had to be put on a firearm license along with a rifle as I think they still are but it would appear that times are changing in England in that one of the ministries dealing with health and safety think its a good idea now to save hearing loss and its now PC and you are not a potential terrorist.
A centre fire rifle with a decent suppressor can bring the noise level down to as if you were firing a 22R/F but of course you don't get rid of the crack of the bullet as it goes through the sound barrier.
Instead of a tin can hanging off the end of a barrel, in NZ suppressors tend to be over barrel or even the full length of the barrel.
