L.E. Wilson
The L.E. Wilson Neck Sizing Die Bushing 335 is a hardened stainless steel neck bushing built for reloaders who demand precision and consistency in their ammunition. Wilson manufactures these bushings in .001" increments, giving you granular control over case neck sizing—essential for match-grade loads and fine-tuning brass that's already seen several reloading cycles. The 335 bushing works with L.E. Wilson neck sizing dies to control how tightly your case neck grips the bullet, directly affecting neck tension and shot-to-shot consistency.
If you're working with brass that's hardened from repeated reloading and no longer holds the bullet with adequate tension, the 335 bushing gives you an unconventional but practical option: flip it over so the markings face the case. Since the bushing is reamed with a .003" taper and only contacts the case at its middle section, reversing it can deliver slightly tighter sizing without stepping down to the next smaller bushing size—a useful trick when you're chasing that last increment of neck tension. This makes the Wilson system ideal for long-range hunters and precision rifle builders who refuse to compromise on brass consistency.
Note that Wilson neck bushings are made to similar specifications as Redding bushings but will not fit Forster or RCBS dies, so confirm your die manufacturer before ordering. The hardened stainless construction stands up to the repeated cycling of serious reloaders, and the precise .001" sizing increments mean you can dial in your loads with confidence.
| Product | Neck Sizing Die Bushing 335 |
| Brand | L.E. Wilson |
| Material | Hardened stainless steel |
| Sizing Increment | .001" |
| Taper | .003" |
| Compatibility | L.E. Wilson neck sizing dies only |
No. L.E. Wilson neck bushings are not compatible with Forster or RCBS dies. They are designed specifically for L.E. Wilson neck sizing dies. Confirm your die manufacturer before ordering.
You can select the proper bushing size two ways: (1) Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003" to allow for brass spring-back and correct neck tension, or (2) measure your case neck wall thickness, multiply by two, add your bullet diameter, and subtract .002" to .003".
Yes. The 335 bushing can be reversed—markings facing toward the case—to achieve slightly tighter sizing. Since the bushing reamed with a .003" taper only contacts the case at its middle section, reversing it is useful as a fine-tuning option if your brass has hardened and no longer holds the bullet adequately, or when you need less squeeze than the next smaller bushing would provide.
Neck tension is how firmly the case neck grips the bullet. Proper neck tension is critical for consistent velocities and accuracy. This bushing controls neck sizing—the physical squeeze applied to the brass—which directly affects the neck tension of your finished round.
