For the highest-quality shotshell presses that provide outstanding reloading, session after session, a high-volume reloader is required. For reloaders, there is an array of different pieces of equipment, tools, and accessories that make loading fun, fast, efficient, and safe. One of these is the MEC bottle, which is always nice to have on hand. In fact, many reloaders will purchase two bottles, keeping one filled with a different size shot or powder, which helps make load changes go quicker. Of course, the manufacturer reminds reloaders to always mark the contents of the bottle clearly to avoid unwanted accidents.
