The L.E. Wilson Neck Sizing Die Bushing 245 is a hardened stainless steel bushing designed for precision reloaders who want tight control over neck tension. If you're working with .245-class cartridges and running a Wilson neck sizing die, this bushing lets you dial in exactly how much your case necks grip the bullet—a level of tuning that generic one-size-fits-all dies simply can't match. Wilson manufactures these bushings in .001" increments, giving you granular control over sizing pressure.
The marked size on the bushing refers to its middle section, which is reamed with a .003" taper. This design means the case neck contacts only the middle portion of the bushing, so you can achieve slightly tighter sizing by flipping the bushing over—markings facing toward the case instead of away. It's a simple trick for fine-tuning when you need less squeeze than the next smaller bushing would give, or when brass has hardened and needs extra control to hold bullets securely. This isn't a daily workaround; it's a precision tool for serious handloaders who understand their brass and their loads.
L.E. Wilson bushings are manufactured to similar specifications as Redding neck bushings, but they are not interchangeable with Forster or RCBS dies—make sure you're running a Wilson die before ordering. To select the correct bushing size, measure your loaded cartridge's neck diameter and subtract .002" to .003", or measure neck wall thickness, double it, add bullet diameter, and subtract .002" to .003". That small spring-back allowance is where proper neck tension lives.
Whether you're building match rounds or hunting loads that demand consistency, a neck sizing bushing gives you the precision that matters downrange. This is reloading at the level where the smallest details shape accuracy.

Frequently Asked Questions
Will this bushing work with my Forster or RCBS neck sizing die?
No. L.E. Wilson neck sizing bushings are not interchangeable with Forster or RCBS dies. Make sure you're running a Wilson neck sizing die before ordering this bushing.
How do I know what size bushing I need?
Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003" to account for brass spring-back. Alternatively, measure your case's neck wall thickness, multiply by two, add the bullet diameter, then subtract .002" to .003". This allows approximately .001" of brass to spring back for correct neck tension.
What does flipping the bushing over do?
The marked size refers to the middle of the bushing, which has a .003" taper. Since the case neck contacts only the middle, you can flip the bushing over—markings facing toward the case—to achieve slightly tighter sizing. This is useful for fine-tuning when you need less squeeze than the next smaller bushing size, or when brass has hardened and needs extra holding power.
Is this bushing the same as a Redding neck bushing?
L.E. Wilson neck bushings are manufactured to similar specifications as Redding neck bushings, but they are designed for L.E. Wilson dies specifically and are not interchangeable with other brands.
