Understanding the Basic Components and Functions
Now, let’s dissect the essential parts of your Mec reloader and how they function, using the Mec Reloader Parts Diagram as our guide:
The Frame/Base
The Frame/Base serves as the foundation of your reloader. It’s the central structure that holds all other components together and provides stability during operation. The diagram will clearly show how the various other components are mounted to the frame.
Die Stations
The Die Stations are arguably the heart of the reloading process. These stations perform the various stages of case preparation, powder charging, and cartridge assembly. Each station is usually dedicated to a specific task:
Sizing or Resizing
The first station is typically dedicated to Sizing or Resizing the brass case. This process involves running the case through a die that brings the case back to its original dimensions, allowing the bullet to seat properly. The diagram will show the die’s location and how it’s secured.
Primer Seating
The next station usually has the Primer Seating operation. Here, a new primer is pressed into the primer pocket of the resized case. The diagram will clearly show the mechanisms for the primer feed system and how it is seated.
Powder Charging
Powder metering happens at a station for Powder Charging. This process involves accurately measuring and dispensing the correct amount of smokeless powder into the case. The diagram will show the powder hopper, metering system, and any adjustments needed to select the proper charge.
Wad Seating
The Wad Seating station follows. This station will ensure the wad gets seated into the case mouth so the shot can sit properly.
Shell Crimping
Finally, the last die station is responsible for Shell Crimping. This step closes the case mouth around the bullet, securing it in place and completing the cartridge. The diagram will show the components involved in this crucial step.
Powder and Shot Systems
Next up, let’s move on to the crucial element of the Powder and Shot Systems. Accurate measurement of the powder and shot is paramount to safety and good performance.
Powder Hopper and Bushings
The Powder Hopper and Bushings are where the powder is stored. The diagram helps you identify the hopper and how the powder flows into the metering system. Selecting the correct powder bushing is essential for dispensing the right charge weight. The diagram will help you visualize how the bushings fit into the system, and often, a chart is included in your manual to guide bushing selection based on the powder type and desired charge weight.
Shot Hopper and Feed
Likewise, the Shot Hopper and Feed provide a place for the shot to be stored and metered.
Primer System
The Primer System is another critical area. Safety is paramount, so proper function of this component is extremely important. The parts diagram reveals the primer feed components and their interaction.
