New Forster Accu-Ring — Laser-Marked for Precision

Forster sizing die lock ring accu-ring accuring laser markings

Forster sizing die lock ring accu-ring accuring laser markingsForster has a new product for precision hand-loaders. The new Forster Accu-Ring has precise markings so you can set your sizing dies with extreme precision in your press. The annodized ring has laser-etched precision markings in .001″ increments. This allows you to more easily set the amount of sizing and shoulder “bump” you get when you move a die up or down in your press.

In addition, if you have a conventional seating die without a micrometer adjustment, this new Forster Accu-Ring can help you achieve more precise bullet seating. SEE Ultimate Reloader Review.

The new Forster Accu-Ring was tested by UltimateReloader.com. The testers tried the new ring with both a sizing die and and seating die. The test confirmed the ring provides greater precision, compared to conventional die lock rings.

See the new Accu-Ring in this Ultimate Reloader product test video released on 10/1/2021:

The product description from Midsouth Shooters explains:

Accu-Ring Cross Bolt Die Lock Ring (Anodized and Laser-Marked)
The Forster Accu-Ring makes setting up your Sizing Die easier by giving you reference marks in thousandth of an inch increments (.001″). To use these reference marks, simply use a fine ink marker to put a point of reference line on your die. Turn the die clockwise to increase the amount of shoulder bump or counterclockwise to decrease the shoulder bump (i.e. increase case’s headspace length).

There are many other factors that could influence the final amount of shoulder bump during sizing. Ductility of the brass or springback, type of case lube used, pulling an expander ball through the neck and the amount of slack in the linkage of your reloading press are a few things that cause variation in shoulder bump of sized cases. The reference marks on your lock ring will help you to zero in on what you want the headspace length of your cases to be.

Remember to lock up the Accu-Ring completely after you make an adjustment before you size a case again. Otherwise you will obtain inconsistent results if the ring is not tightened.

Another use is for non-micrometer seating dies. Instead of guessing with your seating stem, you can make fine adjustments to your seating depths using the Accu-Ring.

The new Forster Accu-Ring retails for $14.99 at Midsouth Shooters.
