Corbin CSW-1 Core Swage Die and Punches
Achieve Precision in Core Weight and Diameter Adjustment
The Corbin CSW-1-S Core Swage Die and Punches are meticulously designed to refine the weight and diameter of cast or cut pure lead cores, ensuring a precise fit for your chosen bullet jackets or any subsequent die set. This die facilitates the adjustment of core weights with an accuracy of less than 0.5%, enhancing the consistency and performance of your ammunition. Add this to any existing die set, or use it as a standalone product to create lead cores with precision.
Key Features:
- Precision Weight Adjustment: Achieves core weight modifications with less than a 0.5% deviation, ensuring uniformity in bullet performance.
- Diameter Customization: Allows tailoring of core diameters to match specific jacket inner diameters, accommodating various bullet designs.
- Integrated Bleed Holes: Equipped with bleed holes to expel excess lead, maintaining die cleanliness and consistent core dimensions.
- Perfect Cylinder: The CSW-1 Die comes with two punches, and external and internal, that have a flat face. This is in order to create a perfect cylinder. Other features can be added to the swaged core with alternative punches but those would need to be a custom order.
Die Compatibility:
The CSW-1-S Core Swage Die is designed for use with the Corbin S-Press, a manual press known for its precision and versatility in bullet swaging. For those using the Mega-Mite or Hydro-Press systems, the corresponding CSW-1-H Core Swage Die is recommended, as these presses utilize different die configurations.
Selecting Core Diameter:
- Known Desired Core Diameter: Enter the specific diameter you aim to produce.
-
Based on Jacket Wall Thickness: Subtract twice the jacket wall thickness from the bullet caliber, then reduce by 0.001 to 0.002 inches for clearance.
Example: For a .458 caliber bullet with a .035-inch jacket wall, the core diameter would be calculated as follows:- .458 (caliber) - (2 × .035 (jacket wall)) - 0.002 (clearance) = .386 inches.
- Uncertain Core Size: Provide the bullet caliber and specify "caliber jacketed" or "caliber lead" to receive guidance on appropriate core dimensions.
Additional Considerations:
- Tubing Jackets: Typically have a .035-inch wall thickness, necessitating cores approximately 0.072 inches smaller than the caliber, plus clearance.
- Lead Bullets: For lead bullets, cores can be slightly larger, e.g., .456 inches for a .458 caliber bullet, to facilitate easy seating in the point-forming die.
Benefits:
- Enhanced Bullet Consistency: Uniform core weights and diameters contribute to improved shooting accuracy and reliability.
- Versatility: Compatible with various jacket types and bullet designs, offering flexibility for different reloading projects.
*Note: Accurate core dimensions are crucial for optimal bullet performance. Consulting with Corbin's technical support or referring to detailed swaging guides is recommended for precise setup and operation.*
