He traced the primer system first. There it was: the Primer Slide (#39), a tiny steel boat that ferried primers from the drop tube to the seating punch. Next to it, the Primer Slide Spring (#40)—a fragile coil no bigger than his pinky. That , he thought. That’s the liar.

But the diagram told a deeper story. To replace #40, you had to remove the Primer Slide Stop Pin (#41). To reach #41, you had to loosen the Carrier Bracket Screws (#58). And those screws shared a line with the Shell Plate Index Pawl (#53). Everything touched everything else. The 366 was not a collection of parts. It was a grammar of motion.

So Arthur did what he always did when a machine lied to him. He reached for the diagram.

Arthur’s eyes drifted to the upper tier: the Powder Slide Assembly (#85–92). The diagram showed the brass powder bushings nested like Russian dolls, the metering insert (#88) drawn with an almost anatomical precision. He remembered buying the machine used, finding an old #88 clogged with Unique powder that had turned to lacquer. The previous owner had never cleaned it. Had never looked at this diagram.

The stroke was crisp. The index was sharp. The primer seated with a sound like a cork popping.
