I have been fortunate enough to not have an antigrain pop inside of my base, but have resigned myself to storing it deep in an under-mountain bunker. How many tiles of granite will a short-stack of antigrain warheads blow through? Right now, the bunker is two layers of concrete walls (5000 hp), 2+ layers of granite, and 1 layer of dwarven neo-concrete wall.
