  N.B

  Therefore Time Shrapnel Shell is the principal

  "Field Artillery" projectile and is carried for most natures

  of Field Artillery

       The best effect from Time Shrapnel is

  obtained when the trajectory passes through of close to

  the target and the position of mean point of burst should

  be close as possible to the target without entailing an

  under proportion of grazes to attain this "Ranging" must

  be carried out till the correct range and length of fuze are

  determined

  In shrapnel shell with base bursters the spread of the bullets

  is principally caused by the rotation of the shell in the 13 Pr

  and 18 Pr shell however, the central tube is filled with powder

  which tends to increase the angle of opening more so it is

  difficult to measure this angle accurately but its tendency is

  to increase as the range increases

  In estimating the front covered by the spread of the bullets

  it may be taken as about 35 per cent of the distance burst

  short or in rough terms the danger zone is if it just

  misses the head of a man it may catch the foot of the

  man behind at a distance of 50 yards
