Here is what I like for hunting limb chickens.
This is a RAR I bought back in July. I put a Nikon P3 EFR 3x9 scope on board, and us CCI SV LR ammo.
This one, I've had for 6-7 yrs. and have shot close to 200 squirrels with it. Unfortunately, it's not made anymore. H&R Sportster single shot .22 LR, with a 2x7 Nikon scope on board. I also use CCI SV LR ammo in it.
