Lyman Neck Expanding (M) Die 9mm Luger/.380 ACP$28.18
Availability: In Stock
The Lyman Neck Expanding (M) Die for .223/.22-250 is a specialized reloading die designed to expand and flare case mouths with precision—a critical step for anyone serious about consistent, high-quality handloads. Unlike a standard expander button that stretches brass, this two-stage expanding die uses a gentler process that preserves case longevity, meaning your brass will survive more reload cycles before it's ready for the scrap bin. If you're working with cast bullets, you'll appreciate that the expanding process eliminates the shaving and material loss that can happen during bullet seating.
Built from hardened steel and heat-treated to Rc 50, this die is engineered to handle the demands of precision rifle reloading. The hand-polished finish—before and after treatment to an 8 RMS surface—ensures smooth operation and reliable performance session after session. Whether you're loading for competition, hunting, or high-volume practice, consistent case neck preparation is foundational to ammo that shoots true.
This die threads into your reloading press and works as part of your overall die setup. Keep in mind that a shellholder is not included, so verify compatibility with your existing reloading equipment or source one separately. The M designation indicates this die is sized for the specified cartridges; confirm your caliber before ordering.
| Caliber | .223/.22-250 |
| Material | Hardened steel, heat-treated to Rc 50 |
| Finish | Hand-polished to 8 RMS before and after heat treatment |
| Shellholder Included | No |
The die is designed to thread into standard reloading presses. Verify that your press and existing shellholder are compatible with the M designation and .223/.22-250 cartridges. A shellholder is not included with this die, so you'll need to source or confirm compatibility with one separately.
A standard expander button stretches the case neck during expansion. This Lyman die uses a two-stage process that expands and flares the case mouth more gently, reducing the stress and work-hardening that eventually causes case failure. Over multiple reload cycles, this translates to cases that last longer.
Yes. One of the primary benefits of this expanding die is that it prevents shaving of bullet material during the seating process—a common problem when using cast projectiles. The controlled expansion ensures a proper fit without the marring that can occur with standard methods.
The Rc 50 heat treatment provides durability and resistance to wear over thousands of reloading cycles. The hand-polished finish to 8 RMS ensures smooth, reliable operation and helps maintain consistency across your entire reloading session.
