Part SE2413 Expander Plug for Lee Precision 9mmp Powder Trough Die.

New stepped expander plug to assist with seating bullets easier. No need to flare as much as this step helps with seating the bullet straight in the case.

Note:

If your die set is not older than 6 months it should have this expander. If you have an older die set you can replace your expander with this new style plug.
