The L.E. Wilson Neck Sizing Die Bushing 247 is a hardened stainless steel bushing engineered for reloaders who demand precision neck control and consistency. Whether you're fine-tuning ammunition for match-grade accuracy or managing brass that's begun to work-harden after multiple reloads, this bushing gives you control that generic dies can't match. L.E. Wilson manufactures their bushings in .001" increments, allowing you to dial in exactly the neck tension your loads need—without stepping up to the next full bushing size and over-sizing your brass.
The engineering here is straightforward but clever. Each bushing features a .003" taper reamed through the middle, so the case neck contacts only that central section. This design opens up a useful option: flip the bushing over (markings facing the case) to achieve a slightly tighter sizing effect without changing bushings. It's mainly an emergency tactic when brass has hardened and lost its grip on the bullet, or when you need to dial in less squeeze than dropping to the next smaller bushing would give you. That flexibility can stretch the life of your brass and help you dial in the exact neck tension your load requires.
L.E. Wilson bushings are built to similar specifications as Redding neck bushings, so if you're familiar with that system, the quality and tolerances will feel familiar. One important note: these do not interchange with Forster or RCBS dies, so verify your reloading press compatibility before ordering. Serious handloaders and benchrest shooters rely on Wilson's reputation for consistency and durability—this bushing carries that same standard.

Frequently Asked Questions
Will this bushing work with my Forster or RCBS reloading dies?
No. L.E. Wilson bushings are not compatible with Forster or RCBS dies. They are designed for L.E. Wilson and Redding die systems. Verify your press and die manufacturer before ordering.
What cartridge is the 247 bushing sized for?
The product record does not specify the cartridge designation for the size 247 bushing. Contact Bosque Outdoors or L.E. Wilson directly to confirm compatibility with your specific caliber and case dimensions.
How do I select the correct bushing size?
L.E. Wilson recommends 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) Alternatively, measure your case neck wall thickness, multiply by two, add your bullet diameter, then subtract .002" to .003". Since bushings are made in .001" increments, you can dial in the exact size your loads need.
When would I flip the bushing over to use it backwards?
Reversing the bushing (markings facing the case) creates a tighter sizing effect by changing where the case neck contacts the .003" taper. This is mainly an option when brass has hardened after multiple reloads and no longer grips the bullet securely, or when you want slightly less squeeze than the next smaller bushing size would provide—without having to buy a new one.
