The Redding 70000 Ultramag Single Stage Reloading Press With Cast Iron Frame is a heavy-duty mechanical reloading tool engineered for precision rifle cartridges, large magnum rounds, and demanding case-forming tasks. Built around a rigid high-grade cast iron frame, the press utilises top-connected compound leverage with heat-treated, precision-ground steel linkage pins to maximise mechanical advantage directly over the centre of the ram stroke. This design prevents frame deflection and maintains concentricity when full-length sizing oversized brass or swaging tough cases. Requiring no electrical power, this manually operated workshop press mounts permanently to benches via a four-bolt base pattern.

Key Features

• Top-Connected Linkage: Connects the compound leverage directly to the top of the frame rather than the bottom, concentrating maximum mechanical force at the end of the stroke without frame flexing.
• Substantial Working Envelope: Features a 4-3/4-inch (approx. 120 mm) frame opening and a 4-1/8-inch (approx. 105 mm) usable ram stroke to clear large magnum calibres and long seating dies.
• Dual Die Compatibility: Accepts standard 7/8"-14 threaded dies using the included steel adapter bushing, and accepts large 1-1/4"-12 threaded dies when the bushing is removed.
• Integrated Spent Primer Handling: Directs deprimed caps down through a hollow steel ram into a clear plastic drop tube to keep the work area and ram bearing clean.
• Smart Priming System: Includes interchangeable primer arm assemblies for seating both large and small primers at the bottom of the stroke for consistent seating depth.

Who is the Redding Ultramag Reloading Press for?

• Precision long range rifle handloaders — requires the 4-1/8 inches usable ram stroke and top-connected linkage of this single-stage reloading press to maintain zero frame deflection when full-length sizing large magnum brass such as .338 Lapua Magnum.
• Dangerous game rifle handloaders — utilizes the 4-3/4 inches frame opening to clear extended cartridge overall lengths and seat bullets in oversized classic Nitro Express and Sharps cases.
• Wildcat cartridge case formers — relies on the 26.3 to 28 lbs cast iron press construction and high compound leverage to perform severe case-forming and bullet-swaging steps without linkage distortion.

Less suitable for: High-volume production handloaders producing hundreds of rounds per hour who require a multi-station turret or progressive press, ultra-heavy .50 BMG loading requiring a dedicated large-scale .50-calibre reloading press, or portable field operations exceeding the limits of a fixed 12 kg bench-mounted press.
