The L.E. Wilson neck sizing die bushing 246 is a hardened stainless steel component built for reloaders who demand precision and control over neck tension. If you're running a progressive or single-stage press with L.E. Wilson dies, this bushing lets you fine-tune how snugly the die grips your case neck—critical for consistent bullet seating and reliable accuracy. Wilson manufactures these bushings in .001" increments, giving you granular options to dial in the exact fit your reloading setup needs.
Neck tension isn't one-size-fits-all. Brass hardening, spring-back variation, and different projectile tolerances all affect how much "squeeze" you want. This bushing is marked with its nominal size, which corresponds to the middle of the bore (reamed with a .003" taper). You can flip it over—markings facing toward the case instead of away—to shift your sizing slightly tighter, a trick that works well when brass has work-hardened or when you need fine-tuning without stepping down to the next smaller bushing size. Made to specs comparable to Redding neck bushings, it integrates seamlessly into L.E. Wilson die systems. Note: these bushings are not compatible with Forster or RCBS dies.
Selecting the right size is straightforward. Measure your loaded cartridge's outside neck diameter and subtract .002" to .003"—that margin accounts for normal brass spring-back and ensures proper neck tension. Alternatively, measure case neck wall thickness, double it, add your bullet diameter, and subtract .002" to .003". Either method gets you close; small adjustments from there dial it in perfectly.
| Brand | L.E. Wilson |
| Product Type | Neck Sizing Die Bushing |
| Bushing Size | 246 |
| Material | Hardened Stainless Steel |
| Size Increment | .001" |
| Bore Taper | .003" |
| Compatibility | L.E. Wilson neck sizing dies only (not compatible with Forster or RCBS) |
No. L.E. Wilson neck bushings are not compatible with Forster or RCBS die systems. You must be using L.E. Wilson neck sizing dies for this bushing to function properly.
Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003"—that gives you the bushing size needed and accounts for brass spring-back. Alternatively, measure your case neck wall thickness, multiply by two, add your bullet diameter, and subtract .002" to .003". The result is your target bushing size.
Yes. The bushing can be flipped so the markings face toward the case (instead of away) to achieve slightly tighter sizing. This is useful for fine-tuning without purchasing the next smaller bushing, especially if your brass has hardened and springs back more than expected.
L.E. Wilson manufactures their bushings in .001" increments with a .003" taper reamed bore. They are made to specs comparable to Redding neck bushings and are designed to integrate seamlessly into L.E. Wilson die systems for repeatable, precise neck tension control.
