Hi I had a lot of break barrels air rifles and used them for hunting (in my country it's legal) so now I sold one of my rifles and want to buy other.I see a lot of videos in the net and read a lot, but I cab choice between .177 and .22 , break barrel or fixed barrel.I will use it to hunt pigeons,crows,magpies and rabbits.I want rifle that can kill on the range of 50-70meters.
