The Wilson chamber type bullet seater is a favorite among benchrest shooters. A chamber type bullet seater positively controls both bullet and cartridge case alignment. The case and bullet are completely captured by the die prior to the bullet being pushed straight into the case by a close-fitting seating stem. This style of bullet seater works more accurately than a conventional 7/8 inch to 14 bullet seating die. This is one of the most accurate bullet seaters ever made! Mfg: L.E. Wilson
