Bullet drop and wind

Damage in SCUM belongs to the round, not to the gun, so what is in the magazine decides the wound. .50 BMG does the most at 400, and 5.56x45mm leaves the barrel fastest at 940 m/s.

Bullet drop and wind

A bullet is not blown sideways at wind speed. It drifts by the crosswind times how much LONGER it took to arrive than a vacuum round would have, which is why drift grows faster than range does. The shooting range on this page draws both the drop and the drift for any round, distance and crosswind, from each round's own muzzle velocity and ballistic coefficient.

How to zero a scope in SCUM

The sight is set for one distance at a time and the scope prints it as ZERO, in metres. Shift and the scroll wheel move it, in steps of 50 or 100 m depending on the weapon, so 400 and 500 are settings and 450 is not. Alt with shift and the scroll wheel move WNDG, the windage, which counts in clicks rather than metres. Holding Ctrl steadies the gun and fills in the block down the left: RNG is how far away he is, WND the wind, then air temperature, humidity, pressure and your altitude. Set ZERO to the range and the crosshair is the answer; leave it short and you are holding over by the figure the range on this page gives you, in metres.

Every SCUM scope and its magnification

A scope steps through its magnifications rather than sliding between them, and the X figure at the top right is the step you are on.

Scope	Magnification	Night vision
Blackhawk Scope	2x	-
SpektralDR	2x / 6x	-
M1 Scope	2.2x	-
Hunting Scope	3x / 6x / 12x	-
PU Scope	3.5x	-
ACOG	4x	-
Improvised Scope	4x	-
P-223 Scope	4x / 8x / 12x	-
ZF39	4x	-
POSP 4x24V	6x	-
Vampyr Scope	6x / 12x / 18x	Night vision

Every kind of round, by calibre

Most calibres come five ways: ordinary, tracer, armour piercing, crafted armour piercing and crafted. 111 kinds in all, each with its own picture on the page. A tracer changes nothing you can measure - it is the same bullet you can see in flight. Armour piercing trades damage for penetration and a plate factor, and the crafted armour piercing round pierces harder still; a crafted ordinary round does less damage than a found one.
