Forster Reloading Dies are of excellent quality and provide the reloader with the ability to produce concentric rounds time and time again. Each die is manufactured from the finest quality steel carefully machined to very tight tolerances. Dies are hand polished both before and after the heat-treating process to guarantee an extra fine finish. All Forster reloading dies feature their Forster Cross Bolt Die Locking Ring that tightens the two ends of the split ring instead of tightening a screw directly into the threads of the die. The Forster Ultra Seater includes all of the features of the Forster Bench Rest Seater Die above, plus an ultra accurate micrometer adjustment. This micrometer adjustment allows you to adjust bullet seating depth from .0005 inch to .001 inch increments, and makes switching bullets easy - just dial back to your previous recorded setting. Forster Ultra Seaters make fine tuning your bullets to the lands of your rifling simple.
