The L.E. Wilson Steel Neck Sizer Die Bushing .327 is a hardened stainless steel neck bushing designed for reloaders who demand precision and control over their sizing operations. If you're working with a Wilson neck sizing die and need to fine-tune how tightly your cases grip bullets, this .327" bushing gives you the adjustability that keeps your ammunition performing consistently shot after shot. Wilson manufactures these bushings in .001" increments, letting you dial in exactly the neck tension your loads require.
What sets Wilson bushings apart is their thoughtful engineering: the marked size refers to the middle of the bushing, which is reamed with a .003" taper. Because the case neck only contacts the middle section during sizing, you can flip the bushing over to achieve slightly tighter sizing if you need it—a useful trick when brass has hardened and started to spring back, or when you're chasing that last bit of precision. This reversibility gives you flexibility without buying multiple bushings. Wilson bushings are constructed to specs similar to Redding neck bushings, though they are not compatible with Forster or RCBS dies, so verify your die manufacturer before purchasing.
Selecting the right bushing size is straightforward: measure your loaded cartridge's neck diameter and subtract .002" to .003" (accounting for normal brass spring-back), or measure your case neck wall thickness, double it, add your bullet diameter, and subtract .002" to .003". Either method gets you the right bushing for consistent, repeatable neck tension that keeps your reloads performing the way you built them.

Frequently Asked Questions
Will this bushing work with my Forster or RCBS neck sizing die?
No. L.E. Wilson bushings are not compatible with Forster or RCBS dies. Verify that you have a Wilson neck sizing die before purchasing this bushing.
How do I choose the right bushing size for my reloads?
Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003" to account for brass spring-back. Alternatively, measure your case neck wall thickness, multiply by two, add your bullet diameter, and subtract .002" to .003". Either method will give you the appropriate bushing size for proper neck tension.
Can I flip this bushing over to get tighter sizing?
Yes. The bushing can be reversed with the markings facing toward the case (markings facing down) to achieve slightly tighter sizing. This is useful when brass has hardened or when you need fine-tuning without switching to the next smaller bushing size.
What's the difference between the marked size and the actual sizing diameter?
The marked size refers to the middle of the bushing, which is the only section that contacts your case neck during sizing. The bushing is reamed with a .003" taper, so the actual sizing diameter varies slightly from top to bottom.
