I got my first deer with a 22 cal but still got her at about 150 yards with a 40 grain hollow point one shot and she went down i saw her try to get up i put the cross hairs on her head and squeezed off another round no more movement when i walked up on her i saw the first shot broke her back and the second took the hole top of her head off 22-250
makes a heck of a wound path so happy for my first white tail good luck folks
