I'm liking the look of the Weihrauch HW77.
For rabbit, pigeon etc would you recommend .22 or .177
…I don't think an air rifle will take out a pheasant!
.22 gives a harder punch for knocking down a rabbit, .177 gives better penetration for getting through the flight muscles of a pigeon. I'd go for .22 and make sure you hit the pigeon in the head!
I'd keep it, Walshy. If it shoots straight & you've got a bit of history then enjoy owning it
As long as you can shoot 1" groups at 25 yards you will hunt successfully and eat well.
