Parts Diagram | Hornady 366

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.

Arthur’s hands smelled of powdered graphite and spent primers. That was the smell of Saturday.

That was the difference between a shooter and a reloader. A shooter saw a tool. A reloader saw a system. He traced the primer system first

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

Arthur wiped the diagram clean of graphite smudges and refolded it along its ancient creases. He slid it back into the manual’s pocket. The 366 wasn’t just a reloading press anymore. It was a map of decisions—Hornady’s engineers on one side, his own repairs on the other. And between them, the trust that came from knowing exactly where every spring, pin, and punch lived.

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.
