The size of the clip can be modified, as can how filled it is on spawn; however, is there any way to adjust the amount spawned with for the “reserve ammo?”
[lua]SWEP.Primary.ClipSize = 5
SWEP.Primary.ClipMax = 10
SWEP.Primary.DefaultClip = 5[/lua]
Something like, [lua]SWEP.Primary.DefaultClipMax[/lua]? That’s as best as I can describe it; Google only netted links to building a SWEP, found no mention of anything like this.
