The L.E. Wilson steel neck sizer die bushing in .263 is a precision reloading component built for handloaders who demand consistency and control over neck tension. Wilson manufactures these hardened stainless steel bushings in .001\" increments, giving you the ability to dial in your brass preparation with minimal guesswork. Unlike generic sizing approaches, a properly matched bushing preserves case life by applying controlled pressure to the bullet—critical when you're working with quality brass and want repeatable accuracy across multiple firings.
The .263 bushing works within the L.E. Wilson neck sizing system, which relies on a .003\" taper reamed into the bushing bore. When you run a case neck through the die in the standard orientation, sizing occurs where the neck passes through the middle of the bushing. For handloaders chasing that extra level of fine-tuning, you can flip the bushing (markings facing the case instead of toward you) to achieve slightly tighter sizing without stepping down to the next smaller bushing size. This dual-orientation feature is especially handy if your brass has hardened and lost some spring-back, or if you're dialing in neck tension for a particular load.\p>
L.E. Wilson bushings are manufactured to specs comparable to Redding neck bushings and are widely respected for their durability and dimensional accuracy. Keep in mind that Wilson bushings do not interchange with Forster or RCBS dies, so confirm your die brand before ordering. If you're already running a Wilson die set or planning to move to one, this .263 bushing gives you a straightforward way to optimize neck sizing and extend the life of your brass.

Frequently Asked Questions
Will this bushing work with my Forster or RCBS neck sizer die?
No. L.E. Wilson neck bushings are not compatible with Forster or RCBS dies. Confirm that you are using an L.E. Wilson neck sizer die before ordering this bushing.
How do I choose the correct bushing size?
There are two methods: (1) Measure the outside neck diameter of a loaded cartridge and subtract .002\" to .003\" to allow for brass spring-back and correct neck tension. (2) Measure your case neck wall thickness, multiply by two, add your bullet diameter, and subtract .002\" to .003\". Both methods account for the approximately .001\" of brass spring-back that occurs after sizing.
Can I use the .263 bushing upside down for different sizing?
Yes. You can flip the bushing so the markings face toward the case (instead of facing you) to achieve slightly tighter sizing. This is useful for fine-tuning neck tension or as an emergency measure if your brass has hardened and lost spring-back. However, this should not be your primary sizing method—it's a supplemental technique.
What is the difference between this bushing and a standard sizer die?
Bushings offer more precise, incremental control over neck tension than a traditional sizer die alone. By selecting a bushing matched to your brass and bullet diameter, you apply only the minimum squeeze needed to hold the bullet securely, which reduces case work-hardening and extends brass life.
