Ammunition
At the beginning of the First World War 60 pounder ammunition scale was 70% shrapnel and 30% HE. The standard shell was 2 crh, but in 1917 a 8 crh shell was adopted.
Subsequently, after the First World War a 56-pound 10 c.r.h. shell to 15,200 yards was introduced. However, its HE content was less than 2/3 that of the various 60 lb shells and it was some 3 inches shorter.
Shrapnel was also varied with bullet weights ranging from 35 to 41 bullets/pound and total loads varying from 616 (Mk ID) to 992 (Mk I) bullets.
Chemical shells were used with 60 pounder but not smoke or incendiary.
