Abstract
An adjustable case sizing die includes a die body having a threaded outer surface and a threaded inner surface. The threaded outer surface of the die body has a first pitch. The threaded inner surface of the die body has a second pitch smaller than the first pitch. A sizing insert is positionable within an interior cavity of the die body. An adjusting spindle is connected to a top of the sizing insert. The adjusting spindle has a threaded outer surface. The threaded outer surface of the adjusting spindle has the same pitch as the inner surface of the die body. The adjusting spindle is threadably insertable into the die body. Turning the adjusting spindle within the die body changes a height of the sizing insert within the die body.
Claims20
An adjustable case sizing die, comprising:
- a die body having a threaded outer surface and a threaded inner surface, the threaded outer surface of the die body having a first pitch, and the threaded inner surface of the die body having a second pitch smaller than the first pitch;
- a sizing insert removably positionable within an interior cavity of the die body and shaped to correspond to an exterior dimension of a case;
- and
- an adjusting spindle having a lower end joined to a top portion of the sizing insert, the adjusting spindle having a threaded outer surface of the same pitch as the inner surface of the die body, wherein the adjusting spindle is threadably insertable into the die body, and wherein turning the adjusting spindle within the die body moves the sizing insert within the die body to change a height of the sizing insert within the die body.
A method for sizing a case, comprising the steps of:
- providing a reloading press having at least one station for accepting a die body;
- threadably inserting at least one die body into the reloading press, the die body having a threaded outer surface and a threaded inner surface, the threaded outer surface of the die body having a first pitch, and the threaded inner surface of the die body having a second pitch smaller than the first pitch;
- threadably inserting an adjusting spindle into the at least one die body, the adjusting spindle having a threaded outer surface having the same pitch as the inner surface of the die body, wherein a lower end of the adjusting spindle is joined to a top portion of a sizing insert, wherein the sizing insert is shaped to correspond to an exterior dimension of a case, and wherein the sizing insert is removably positionable within an interior cavity of the die body;
- turning the adjusting spindle within the die body to move the sizing insert within the die body, thereby changing a height of the sizing insert within the die body to correspond to a case height specification;
- and
- pressing a case into the sizing insert, thereby sizing the case to the case height specification.
