The Redding Big Boss II Reloading Press (Model 97000) is a single-stage reloading press built with a high-density, heavy-duty cast iron O-frame. Engineered for mechanical leverage and precise alignment, the frame features a 36-degree offset angle that offers clear visibility and unhindered access to the shellholder. The press handles standard full-length resizing, case forming, and precision bullet seating for cartridges ranging from small pistol calibers up to large magnum rifle cases.

Key Features

• High-Density Cast Iron Frame: Features a rigid O-frame configuration weighing approximately 19.64 lbs (~8.9 kg) to eliminate frame flex during heavy resizing operations.
• Offset Working Window: The 36-degree frame tilt and ergonomic ball handle provide clear line-of-sight and direct hand access to cases.
• Dual Thread Compatibility: Includes a factory-installed removable steel bushing to accept standard 7/8"-14 threaded dies, which can be removed to accommodate oversized 1-1/4"-12 threaded dies.
• Through-Ram Spent Primer Disposal: Directs spent primers and carbon residue straight through the hollow 1.0-inch ram into a flexible plastic collection tube, preventing fouling on the mechanical linkage.
• Integrated Primer Arm: Features a "Smart" priming system that automatically swings into position during the stroke for on-press primer seating.
• Mechanical Compound Linkage: Delivers high mechanical advantage to resize tough rifle brass with minimal operator effort.

Who is the Redding Big Boss II Reloading Press for?

• Precision rifle reloaders: Requires precise concentricity and low runout for benchrest, PRS, and F-Class competition brass, supported by this single-stage press's rigid cast-iron O-frame and 1.0-inch-diameter ground ram.
• Long-range hunters: Requires the clearance and mechanical leverage to full-length resize standard up to large magnum hunting cartridges, delivered by this single-stage reloading press via its 4.5-inch frame opening and 3.8-inch usable stroke.

Less suitable for: High-volume bulk reloading exceeding 100 rounds per hour, where a progressive multi-station reloading press is recommended; or ultra-oversized extreme long-range calibers such as .50 BMG that exceed a 1-1/4"-12 thread, where a dedicated extra-tall .50 BMG press is required.
