Lee-Enfield Service Rifle
Military Engineering (Part 1), Field Defences, 1908
The service rifle is the Lee-Enfield. It is universal for all arms. Length, 3 ft, 8 ½ in. men muzzle velocity about 2,000 f.s. Its calibre is .303-in.
The slopes of descent of the bullet at various ranges are roughly:—
- At 1000 yards, 1 in 30.
- At 1500 yards, 1 in 12.
- At 2000 yards, 1 in 6.5.
- At 2500 yards, 1 in 3.
- At 2800 yards, 1 in 2.5.
The following table gives the thickness in various materials, proof against a bullet fired from the short Lee-Enfield Service Rifle at 30 yards range. The bullets of some continental armies have, however, greater penetration.
| Material. | Thickness proof. | Remarks. |
| Clay | 5' | Varies greatly. This is maximum for greasy clay. |
| Earth free from stones (un-rammed) | 3' | Ramming earth reduces its resisting power. |
| Sand | 2' 6" | Rather more than enough. Very high velocity bullet have less penetration in sand at short than at medium ranges. |
| Sand (between boards) | 18" | |
| Brickwork | 9" | If well built. |
| Soft wood, e.g., fir | 48" | 24" proof at 500 yards. |
| Hard wood, e.g., oak | 27" | 15" proof at 500 yards. |
| Wrought iron, or mild steel | 1/2" | |
| Hardened steel plate | 1/4" | 1/10" proof at 600 yards. |
| Special hard steel | 1/5" | |
| Shingle | 6" | |
| Coal (steam) | 2' 6" | |
| Chalk | 1' | When freshly excavated. |
