Here is sad news.
We had the first murder of the year, and it was a guncrime

and a puny .22 normal, BRNO bolt action. One shot.
No supressor or silencer, since the killer was not really thinking about it I guess. I think we can have them anyway, and if not, they're easy to make.
Then, he went away and shot himself. Also dead.
2x22 bullets and two corpses. The victim almost survived though, but tough luck, even .22's do a lot to big arteries.
Terrible. And the whole circumstances were quite dramatic.
Anyway, of silencers. I once tried a .22 automatic, with a scope and a silencer. Now that is one for the grouse or ptarmigans. It only makes a slight click and a "pfft" and a "thump" where the bullets hit. If you are hid or still, the birds will look and not fly. You wait a few secs then fire again.
If you pick them off with a rifle as well, and hit the chest nicely, you won't have to be chewing on them pellets as well when you eat them.
