FIXING THE BAYONET:
Musketry Regulations inform us that with the “S.M.L.E.” the effect of fixing the bayonet is to throw your shot 18 inches high at 200 yards’ range. This is because the extra weight slows down the vibration, and thus converts a negative into a positive jump. Hence, as a Sniper, you will fire without your bayonet fixed.
(Note:—From tests carried out at this First Army School of S.O.S. it would appear that Musketry regulations greatly over-estimate the effect caused by fixing the bayonet.)
HOLD:
Unless the Sniper reproduces the same hold for each shot and when he rests his rifle rests it always at the same point (for preference the middle band), his shooting can never be consistent.
AMMUNITION:
Different makes of S.A.A. give slightly different elevations on the target. This is because the Powders burn at different rates, thus slightly altering the jump.
WARPED WOODWORK:
The fore-end is fitted so as not to influence the barrel when firing. The barrel must be able to lie perfectly straight as each shot leaves it. If the fore-end is warped (and warped fore-ends are common) the barrel will be unable to lie as was intended, and erratic shooting will result.
