Because its base damage is bullet type, which means its damage is reduced by armor, and the grineer get stupidly huge amounts of armor after just a few levels. A medium grineer has enough armor at even low levels to reduce bullet damage by about two thirds. At higher levels you can almost see the rounds ricocheting off them. Armor piercing, however ignores armor when calculating damage dealt, plus the grineer have an elemental weakness to it (1.5x more damage) so it is much more effective.
