RCBS 6.5 x 55 Swedish Mauser Gold Medal Full Length Bushing 2-Die Set, Group A
RCBS® is proud to introduce the Gold Medal series of neck bushing rifle dies. This changeable diameter neck bushing type of die has been used by Bench Rest and Long Range Precision shooters for years.
Due to variability in neck brass thickness, RCBS standard dies size the neck below your desired diameter and then pull an expander ball through to get the proper bullet tension. The Gold Medal sizing die features a self-centering, changeable neck bushing that allows you to precisely set the amount of tension on the bullet. This reduces work hardening of the case neck brass, prolonging case life and increasing accuracy. Neck bushings are available in .001” increments from .189” to .365”.
The Gold Medal rifle dies are available in Full-Length and Neck sizing styles. By removing the neck bushing, the Full-Length sizing die can be used as a “bump” die to set headspace back to desired amount.
The Gold Medal seat dies features a micrometer adjustable, free floating and self centering bullet seating system with a convenient bullet loading window. The Gold Medal seat die can also be used on progressive presses with the exception of the .221 Rem Fireball and .22 Hornet cartridges.
How to Determine Which Bushings You Need:
The easiest way to determine the proper diameter bushing, is to measure the neck diameter of several loaded or dummy cartridges with an accurate micrometer. Subtract .001”- .002” from the average neck diameter and this diameter bushing will generally size case necks to create the proper press fit for the bullet.
Another method is to measure the neck thickness with a ball micrometer. Double the wall thickness and add this number to the bullet diameter. The result is the neck diameter of a loaded cartridge, and bushing size can be determined as above.
