Forster Datum Dial Kit

The Forster Datum Dial Kit makes it possible for the handloader or gunsmith to use ordinary dial calipers to make normally difficult length measurements based on the case shoulder. By measuring cases to the datum line on the shoulder, the reloader can custom-fit the ammunition to a rifle’s chamber for the best possible fit for better accuracy potential and longer case life.

The gold “bullet dials” makes it easy to accurately determine bullet seating depth measured from the ogive when changing the seater die setting or when checking loaded rounds for consistency. It can also be used to check the bullets alone for variations that could hurt accuracy.

The Complete Kit includes the Body with Case Dial for checking cases and two Bullet/Cartridge Dials. The #1 dial fits 224, 243, 264, 284, and 308 calibers. The #2 dial fits 172, 204, 257, 277, and 338.

Gunsmiths can easily check the length of customers reloads verses the chamber.  Seating depth verses throat, and uniformity of ammunition.  All errors that can make problems hard to diagnose.

This kit can also be used to double check headspace gauges if questions arise.

Included are complete instructions, storage box, and a laminated chart with common datum diameters.
