These mandrels are interchangeable, allowing reloaders to customize the neck tension to suit their specific needs. Crafted from 17-4PH Stainless Steel and treated with black nitriding, our mandrels ensure smooth, reliable and long-lasting performance. This robust construction enhances durability and guarantees a smooth operation, making them ideal for precision reloading.
