The RCBS X Die Full Length Set for 6.5x55 is a premium reloading die set engineered for shooters who demand consistent, accurate ammunition. Built around RCBS's mandrel-based design, this full-length set streamlines the reloading process by managing case neck growth and eliminating redundant trimming steps—a genuine time-saver for high-volume handloaders and precision rifle enthusiasts working with the 6.5x55 cartridge.
What sets the X Die apart is its mandrel technology. During sizing, the mandrel contacts the case mouth to reduce neck growth rate and prevent the neck wall thickening that occurs with conventional full-length dies. After your initial trim of 0.02 inches from maximum case length, the mandrel's close tolerance to the neck wall means you won't need to trim again for several reloads—a workflow advantage that pays dividends if you're processing brass in volume.
Whether you're loading for target work, hunting, or long-range precision shooting, consistent case preparation is foundational to accuracy. The X Die's mandrel approach delivers that consistency without the back-and-forth of traditional full-length sizing followed by separate neck trimming. This is the kind of incremental efficiency that compounds across hundreds of rounds.

Frequently Asked Questions
How does the mandrel reduce case trimming?
The mandrel contacts the case mouth during sizing and reduces neck growth rate. After your initial 0.02-inch trim from maximum case length, the mandrel's close tolerance to the neck wall prevents further growth for multiple reloading cycles, so you don't need to trim again as often as you would with a standard full-length die.
Will this die set work for high-volume reloading?
Yes. The mandrel design is especially valuable for shooters processing large quantities of brass, since it eliminates the stop-and-trim cycle between sizing and loading. You can size multiple rounds before trimming becomes necessary again.
What's included in the full-length set?
