The Lee Powder Through Expanding Die in .40 S&W / 10mm Auto (Lee part no. 90620) combines two reloading steps into one station: it expands the case mouth to accept a bullet while simultaneously charging the case with powder through a powder funnel adapter or an Auto Disk / Pro Auto Disk Powder Measure mounted on top. For handloaders running a turret or progressive press, cutting that extra step out of the cycle speeds up loading sessions without giving up a controlled, consistent case mouth flare for the bullet to seat into cleanly.

Key Specifications

Frequently Asked Questions

Does this die replace my expander die? Yes, it expands the case mouth and drops a powder charge in the same step, so a separate expander is not needed.

What do I need to mount on top of it to charge powder? A powder funnel adapter or a Lee Auto Disk / Pro Auto Disk Powder Measure feeds powder through the die as the case expands.
