For any non-integer magazine values the magazine size is simply rounded to the nearest whole number. For example, a Strun modded with a max rank Burdened Magazine will have a calculated magazine size of 6 × (1 + 60%) = 9.6, which will simply round to 10.
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.
