MEC is known for making high-quality, long-lasting shotshell presses that work great for beginning shotshell reloaders to the most advanced high-volume shotshell reloader. These quick-change charge bars are made from anodized aluminum and are for use with removable powder charge bushings (sold separately) to adjust powder charges. They feature a soft insert to avoid shearing larger or hard shot. Lead and Steel Shot charge bars are not interchangeable.
