Rabbits are no big deal to shoot or at least they werent when I was a kid as they were in their millions way back then.
I shot my first several thousand rabbits all with a Lithgow single shot .22 rifle with of course open sights.
Once one gets the hang of it it wasnt any big deal to head shoot rabbits out to 50 yards and even stretching the barrel for a lot longer shots when all the stars were aligned.I gat my arse kicked by the old man if I didnt head shoot them,it worked and laid the foundation for bigger and better things to come,although I used a scope on a Fallow buck yesterday...
