The L.E. Wilson Neck Sizing Die Bushing 248 is a hardened stainless steel bushing designed for reloaders who need precision control over neck tension. If you're running a Wilson neck sizing die and want to fine-tune how snugly your brass grips the bullet, or if you're working with brass that's hardened and lost its spring-back, this .248" bushing gives you options that off-the-shelf dies often can't match. Wilson manufactures these bushings in .001" increments, so you get exact sizing control without jumping to the next standard die size.

The marked diameter on the bushing refers to the middle section, which is reamed with a .003" taper. This taper design means you can reverse the bushing—markings facing toward the case instead of up—to achieve a slightly tighter sizing fit. That technique is handy when you're chasing that last fraction of neck tension, or when your brass has work-hardened and won't cooperate with normal sizing. Most reloaders use this as a fine-tuning tool rather than a daily workaround, but it's there when you need it.

These bushings are manufactured to specs comparable to Redding neck bushings and will work with any Wilson neck sizing die, but they will not fit Forster or RCBS dies. If you're already invested in Wilson equipment, this bushing integrates seamlessly into your setup. Selecting the right size comes down to either measuring your loaded cartridge neck diameter and subtracting .002"–.003", or calculating from your case neck wall thickness and bullet diameter. Either method accounts for the natural spring-back of brass and gets you into the sweet spot for consistent neck tension across your reloading runs.
