The 155mm semisteel howitzer chemical round had a blunt nose, the radius of which was 1.5 calibers. The portion at the rear of the rotating band was cylindrical. This round did not contain a base cover. The threads in the nose for the adapter and booster were either tapered or pipe threads. The adapter and booster were tightly screwed into place to minimize the likelihood of leakage.
