Product Info for Forster Datum Dial

Forster Datum Dials are the easiest way to measure cartridge case lengths and ensure that your handgun is functioning properly. These Reloading Tools by Forster are useful both before and after sizing your weapon. The Forster Ammo Measuring Dial System lets you transfer a measurement from the base of a case to a datum point on its shoulder angle, providing a relative measurement. This type of measurement is useful because it allows you to find the optimum headspace for your weapon. This Forster Dial System w/ Interchangable Dials is incredibly easy to use and setup, and it can cover a number of calibers. Forster Action Products offers this type of Dial System in a special storage box that keeps all the components together and protected. Forster offers this same type of Dial System in many of their kits, but they often contain many more parts. Forster knows that reloaders need a versatile ammo measurement system, or else they would have to purchase a completely different set for each type of weapon they want to reload. The Forster Satin Dial covers multiple calibers, including 17 cal, 204, 243, 257, 264, 277, 284, 308, and 338.image
