Lyman MSR Precision 3-Die Set Reloading Dies

Lyman MSR resizing die is specifically designed for self-loading/semi-automatic rifles, such as AR-15 type firearms.

If you've experienced issues with other dies not providing sufficient resizing, or if you know your chamber is tight, the MSR die set's Small Base resizing die resizes the case from a longer distance than a standard resizing die. This ensures more reliable ammunition feeding in self-loading firearms.

The package also includes:

- Taper crimp die for bullet seating
- Bullet seating die
- Cartridge gauge "GO"

 450 Bushmaster and 458 Socom come as 4-die sets.

NOTE!! The Small Base resizing die increases the risk of case sticking in the die, as it resizes the case more and over a longer distance. Therefore, use sufficient high-quality case lube during resizing to prevent this issue.
