Hi I'm AirZingis, and I will waste bullets on primaries so that the max ammo in a mag and the reserves add together for a number ending in 0. For example, if the max amount of bullets in a gun's mag is 36, and there's 203 bullets in reserve, I'll shoot 9 shots so that when I reload, there will be 36 in the mag and 194 in reserves. Those two added equals 230.
