I started reading Guns and Ammo in 1970 and from then on understood "plinking" to mean the American equivalent of our shooting tin cans, in the garden, with an air rifle- only difference being they used .22lr. Yes our American cousins are a little different from us a few years ago I had an American client for stags, he chose to take advantage of the estate rifle clause, my local police required a reference from his local police chief pertaining to his good character, before issuing a UK visitors permit allowing him to bring his rifle into the country. For reasons best known to himself he chose not to do so, but to use the estate rifle. On the first morning we went to the target before going to the hill in search of a stag I produced the rifle explaining the operation of the safety catch, in case he was not familiar with that types operation. What calibre is it he asked? .243 I replied! WHAT he exclaimed my twelve year old son has one of those for shooting squirrels in the back yard.
