The "Big Boss" press is a larger version of the popular Boss Reloading Press. Its heavy duty cast iron frame with 1" diameter ram has over 3.8" of stroke. This press will handle all your reloading for large magnum cases and has a large ball handle arm for ease of operation. The offset O-frame makes getting cases in and out of the press easy when compared to other presses on the market. This is one of the best presses for all around reloading. SINCLAIR TECH TIP: To keep your 7/8-14 press running smoothly and last longer, periodically clean and de-grease the ram with a solvent (QuickScrub works well - SC-QS2 @ $6.50). Then coat the ram with an oil or light grease. A heavy grease tends to attract more chips and debris.
