After viewing the explosive and regular dwarven bolts one right after the other in the inventory in-game, I noticed that the dwarven bolt quiver looked unusually round looking compared to the explosives. Peering into NIFSkope, I discovered that I forgot to generate a complete tangent space for the regular's quiver. Tangent space data is important for rendering normal maps, and having an incomplete one can make them look... off. v1.0.1 has a fully formed tangent space in the errant mesh now.
