In 1953 i inherited a model 70 Winchester in .220 Swift caliber; made in 1939. The gun was re-barreled by the Winchester factory in 1965 and again in the mid 1970s. My other .220 Swift is a Ruger model 77. Not long ago i took that old Winchester to the range for the first time in many years. The first 5 shot group fired at 100 meters measured .7". After firing that group i quit shooting, came home, cleaned the gun and put it away. It will be going back to the range again soon.
Buy the lady a .220 Swift.
