RE: .22 Hornet
If I had money for everything, I would get one. Kind of tugs on the heart strings from dad's rabbit hunting days in Nebraska. If you don't reload you might try Winchester's soft point. The Hornet will reach out and get them in the flats where the .22 LR does not have the range. A scope will get you the head shots. And some of the 22 hornet rifles (drool) have the quality. Not noisy, either. Pricy shooting for a rabbit, but then, I like fried rabbit and.... biscuits!!
Would like to hear what rifles you are looking at.
