The Hornady Primer Punch - Large (MPN: 390035) is an OEM replacement mechanical reloading component manufactured from precision-machined hardened steel. Designed as an integral part of Hornady’s Positive Priming System (PPS), this sub-ounce pin-and-base assembly measures under 2 inches in length and mounts inside the primer arm mechanism of compatible single-stage presses. It provides flat, uniform seating leverage to seat primers below flush in centerfire cartridge primer pockets, preventing high primers and ignition failures during batch reloading operations.
Key Features
- OEM Positive Priming System Component: Functions as a direct drop-in replacement part inside the press swing-arm assembly alongside the Large Primer Cup (#390006) and primer cup spring (#390007).
- Precision Hardened Steel: Machined from hardened steel to resist deformation, bending, and wear during repetitive on-press priming strokes.
- Below-Flush Seating: Delivers square mechanical leverage against primer cups to seat primers consistently below the cartridge case head across batch operations of 50 to 200 rounds.
- Fully Mechanical Operation: Requires no external power supply or electrical connections for manual, on-press priming at the ram stroke.
