HORNADY PTX™ Universal Powder Drop Expander .357 #290031

The powder through expanders (Ptx) are designed to work with the powder dispenser activated by the case. These expanders eliminate the need for a separate expander for the case mouth on the Lock-N-Load Ap press, freeing up a station for crimping. The expanders work well for bare lead, copper-plated, or jacketed bullets.
