Methods and apparatus are provided for dispensing chemical material, and in particular, granular, agricultural material, from a moving device driven over terrain to be treated with the material. In an exemplary parachute, a shoulder panel is disposed between a center panel and a side panel to at least partially equalize load path lengths in the cruciform parachute. The ammunition is advantageously used with an industrial ballistic tool operating so that each spent case serves as the effective projectile to be propelled by firing of the next round of ammunition.
