Hornady 366 Parts Diagram [top] -

Before we dive into the wads and primers, understand that the Hornady 366 is a "progressive" press. This means one pull of the handle performs five or six operations simultaneously: sizing, depriming, repriming, powder dropping, wad insertion, shot dropping, and crimping.

Many reloaders rely on their memory when disassembling their press. They lay out springs, screws, and pins, confident they will remember where everything goes. Three days later, they are left with a "mystery spring" and a press that won't cycle. hornady 366 parts diagram
