The Forster Bushing Bump Kit & Ultra™ Seater Die Set includes both their popular Ultra™ Seater die, as well as their Bushing Bump Neck Sizer die. This kit also comes with 3 Neck Sizing Bushings; one for the bullet diameter, one that is .002" over and one .002" under the bullet diameter. This kit contains everything you need to dial in the correct neck tension and get the most accuracy out of your loads. The Forster Ultra Seater includes all of the features of the Forster Bench Rest Seater Die 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. Forster's Precision Bushing Bump Dies size the case neck and adjust the headspace length without sizing the body of the case. Includes a decapping assembly without an expander ball so your bushing selection determines the internal neck diameter. All Forster dies are hand polished both before and after the heat-treating process to guarantee an extra fine finish. All Forster reloading dies feature Forsters 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.
