APW Precision Mandrels

Each set includes two mandrels, one with a diameter reduction of -0.001 inches and the other with a diameter reduction of -0.002 inches. These precise measurements allow you to achieve optimal bullet tension and ensure consistent results with your reloading process.

Using an expander mandrel in your reloading process offers several key benefits for long-range shooting and consistent reloading:

1. Improved Bullet Seating: The expander mandrel ensures consistent and precise bullet seating by expanding the inside diameter of the case neck. This promotes a secure grip on the bullet, minimizing bullet runout and enhancing accuracy downrange.
2. Enhanced Bullet Tension Control: The use of an expander mandrel allows you to fine-tune the amount of neck tension on the bullet. This is crucial for long-range shooting, as it helps maintain consistent bullet release from the case neck, resulting in more predictable and repeatable ballistic performance.
3. Consistency in Neck Tension: By utilizing an expander mandrel, you can achieve uniform neck tension across your reloading batches. Consistent neck tension is vital for ensuring uniform bullet release and optimal chambering, which directly impacts shot-to-shot consistency and accuracy.
4. Case Neck Annealing: When combined with proper case neck annealing techniques, the expander mandrel helps to restore and maintain consistent neck tension throughout multiple reloadings. This prolongs the life of your cases and ensures consistent bullet seating from shot to shot.
5. Customisation and Versatility: Expander mandrels are available in various diameters, allowing you to select the optimal size for your specific bullet and case combination. This customization enables you to achieve the desired neck tension for different loads and bullet types, optimizing performance for different shooting applications.
6. Reloading Efficiency: The use of an expander mandrel streamlines the reloading process by ensuring consistent neck tension, reducing the need for additional adjustments and resulting in more efficient reloading sessions.

In summary, incorporating an expander mandrel into your reloading routine for long-range shooting and consistent reloading offers improved bullet seating, enhanced bullet tension control, consistent neck tension, customization options, and increased reloading efficiency. These benefits contribute to more accurate and predictable results, ultimately enhancing your shooting performance on the range or in the field.
