THE TESTS

This section will be expanded when time permits. More than five hundred tests were undertaken for four editions of The Airgun Book, 'Airgun Scene' and Airgun Shooting A-Z in the 1980s and 1990s, but the data was thought to have been lost until some of the relevant papers were unexpectedly rediscovered in 2014.


Above: a typical set of velocity/velocity loss/accuracy correlation results presented graphically. Below: velocity and consistency results of typical (but not necessarily best) 25-shot strings. The way in which consistency ('vdi') is calculated is explained in two of the reprinted articles. Any 'vdi' figure bettering 1·0 should be regarded as good.
