Lee Precision 90541 Pacesetter 3-Die Set 7x57mm Mauser Reloading

The Lee Precision 90541 Pacesetter 3-Die Set delivers consistent ammunition production for 7x57mm Mauser cartridges. This complete reloading system combines precision engineering with affordable pricing, making it accessible for shooters who demand reliable performance without premium costs.

What Makes This Different

The Pacesetter series features Lee's factory crimp die technology, which applies uniform case mouth pressure that standard taper crimp dies cannot match. Each die undergoes precision machining to maintain concentricity within 0.002 inches, ensuring consistent bullet seating and improved accuracy. The included powder through expanding die streamlines the reloading process by allowing powder charging and case mouth expansion in a single operation.

Key Features

• Factory crimp die provides superior bullet retention and consistent neck tension
• Powder through expanding die combines case expansion and powder charging steps
• Full length sizing die with decapping pin removes spent primers and resizes cases
• Precision-machined steel construction with corrosion-resistant finish
• Standard 7/8-14 threading fits most single-stage and turret presses
• Includes detailed instructions with load data and safety guidelines
• Compatible with Lee Auto Prime hand priming tools and powder measures

Field testing demonstrates that ammunition produced with this die set maintains velocity spreads under 30 fps when paired with quality components and consistent techniques. The factory crimp die particularly benefits hunting loads, where bullet retention during magazine cycling and chambering proves critical for reliable feeding. Competition shooters appreciate the consistent case preparation that supports sub-MOA accuracy potential in precision rifles.
