Wilson Expanding Mandrel Die

Wilson Expanding Mandrel Die

The Wilson Expanding Mandrel Die is one of the most versatile and useful reloading tools you will ever own. This die can be used to straighten NEW brass cases prior to the seating operation. It can also be used in conjunction with bushing dies and standard sizing dies to ensure that the inside diameter of the cases are consistent with each other. This important step can make sure bullet grip is equal for all your rounds which converts over to more consistent chamber pressures and thus improves accuracy.

New brass cases whether bulk or high-end carefully packaged brass inevitably have dents or creases in the case neck. This die can be used to iron out and straighten the necks prior to first loading. Many reloaders also use these dies in forming cases from a smaller caliber to a larger caliber. Usually done with one progression at a time. (example – 6 mm expanded to 6.5 mm). This die comes with one mandrel (specific caliber). Additional mandrels are available for other calibers. This die is made to work in standard 7/8”-14 reloading presses.

The most important function of this die is worth repeating! It makes sure your case neck tension/bullet grip is as consistent as possible from round to round which will improve your standard deviation and precision grouping at the target.
