My bergara’s favorite - Winchester Wildcat .22 Long Rifle 40 Grain Copper Plated Rimfire Ammunition

This is the least expensive ammo that has been 100% dependable in my BXR (Bergara version of a 10/22). It is also the most accurate of the ten different .22 offerings that I have tried from Federal, Winchester, CCI, etc.
So when you are after duck or rabbit, bring your hunting dog. Anything smaller... bring the Wildcat.
