Gun Powder C is the primary component to creating the varying Grenade Launcher rounds, using different combinations of powder. The exception being the usage of three Gun Powder Cs, which produces Magnum ammo. Maximum amount of Gun Powder C, player can obtain through mixing Gun Powder A with B, is seventeen (because maximum amount of Gun Powder B is 17).

Also, there is a direct connection between those mixes and combinations of Gun Powder with Explosive Grenade Rounds (A + G.R.; AA + G.R.; AAA + G.R.; B + G.R.; BB + G.R.; BBB + G.R.; C + G.R.; CC + G.R.; CCC + G.R.) that also give the same point of experience.
- 1-3 = 10 x Grenade Rounds
- 4-6 = 11 x Grenade Rounds
- 7-11 = 13 x Grenade Rounds
- 12+ = 15 x Grenade Rounds
If three mixed Gunpowder C (CCC) are combined with the Reloading Tool, it will produce 24 Magnum Bullets.
