hi-ive been shooting rabbits for over 30 years so i guess i should offer my pennys-worth-buy a cz 452 (brno)-you can pick them up for peanuts and unless they are completley sh****d (which is very rare) they will pop rabbits at 100 yards all day long-when you apply for your FAC (and its much easier than most people would have you believe) dont forget to apply for the silencer as well or you will have to apply at a later date and it will cost you-ask about hollow-point ammo as well cos i seem to remember that i had to make an application for that -shooting rabbits with a rimfire is about as much fun as you can have with your trousers on -good luck-bruno.
