The Forster Bushing Bump Kit & Bench Rest® Seater Die Set includes both their popular Bench Rest 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. Forster Bench Rest Seater Dies were the first of their kind to utilize a close fitting chamber that holds the case, the bullet and the seating stem all in perfect alignment. This support system allows the reloader to produce exceptionally straight ammunition. Conventional seating dies with a fixed chamber and seating system may start your bullet into the case neck at an angle. They lack the support the Forster Bench Rest Seater provides. 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. Forster Bench Rest 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.
