RCBS Rifle X-Die X Sizer Two Die Set

Trim the case once - never trim again! The X-Sizer Die looks like a regular Full Length Sizer Die. Inside, the die features a specially designed mandrel with an expander ball and decapping pin attached. The mandrel is what the X-Die is all about. The patented X-Sizer Die eliminates the need for repeated trimming after initial trim of .020" off the maximum case length to standardize the case.

The X-Die doesn't shorten the length of the case: the mandrel reduces the growth rate as the case grows as a result of the case mouth contacting the mandrel during sizing. Because of an extremely close tolerance between the mandrel and die neck wall, the neck wall of the case odes not thicken as the case length is pushed back.

Cases repeatedly sized in the X-Die will initially grow a few thousandths of an inch, then stabilize below the maximum case length with no discernible loss of accuracy or case life.

RCBS® was founded from a hobby, by Fred T. Huntington, in the early 1940's.

Originally located in the back room of his father's Oroville laundry on High Street, RCBS soon outgrew this modest beginning and in 1947 was relocated to Fred's garage on 7th Avenue. The business continued to grow quite rapidly, and several more moves took place. Today, RCBS is housed in about 110,000 square feet of building.

The very first RCBS dies were specifically designed to form jacketed bullets from fired .22 caliber copper cases. Because these bullets were used to shoot Rock Chucks - a varmint of the Western United States - RCBS named these dies Rock Chuck Bullet Swage, later shortened to RCBS.

Although they no longer manufacture bullet-swaging dies, RCBS is the leading manufacturer of ammunition reloading equipment for rifles and pistols. The brass case is the most expensive part of a loaded round, and when reloaded, offers savings of about 60% over factory-loaded ammunition. RCBS sells reloading equipment throughout the world and currently has a work force of one hundred employees.

RCBS was acquired by Omark Industries in July, 1976 and became part of the Sporting Equipment Division. In 1985, Omark Industries was in turn purchased by Blount, Inc.

In December of 2001, Alliant Tech Systems purchased RCBS. ATK is a leading provider of advanced weapon and space systems with approximately 15,000 employees and operations in twenty-two states. The company is the world's leading supplier of solid propulsion systems and the nation's largest manufacturer of ammunition. RCBS is part of ATK Civil Ammunition Group.
