For some weapons, a 10% increase (or a multiple thereof) in magazine capacity results in a non-integer number. When this happens, the number is rounded to the nearest integer where 0.5 is rounded up. The following table shows the specific increase in capacity of certain weapons.
Could make one magazine last entire fights without needing any reloads, thus nullifying the negative reload speed.
Combining this mod and Ammo Stock would give +120% magazine size to the modded shotgun.
Unlike Tainted Mag and Tainted Clip, this mod increases the magazine size just as much as the non-corrupt counterpart, hence it should only be used in conjunction with Ammo Stock in builds aiming to maximize magazine size.
With this mod and Ammo Stock, Tigris and it's variants can reach a magazine size of 4. With a rank 5 Ammo Stock, Burdened Magazine can be left at rank 1 to minimize the reload penalty and capacity drain.
