The Forster full length die sets comprise the ultra micrometer seater die and a full length sizing die. Each Forster full length sizing die is equipped with an E-Z Out Expander button, designed to maintain concentricity of case necks during the neck expanding process. This button is strategically positioned higher in the neck area compared to most other dies, providing support and ensuring alignment of the neck and case axis as the case is withdrawn from the die. The Forster ultra seater incorporates all features of the Forster Bench Rest Seater Die, with the addition of an ultra-precise micrometer adjustment. This adjustment facilitates bullet seating depth modifications in increments ranging from 0.0005 inches - 0.001 inches, allowing for easy bullet switching by reverting to previously recorded settings. The Forster Ultra Seaters simplify the fine-tuning of bullets to the lands of your rifling. These dies utilize 1-1/4 inches threads, which are larger than standard reloading dies and are intended for use with presses that have similar threading, such as the Forster Co-Ax XL press. This kit comprises a full-length sizing die and an ultra seater die, engineered with Forster's renowned precision manufacturing standards and is housed in our premium deluxe die box for optimal protection
