MEC 8042 Magnum Shot/Powder Bottle Universal Large - High-Capacity Reloading Container

The MEC 8042 Magnum Shot/Powder Bottle is a high-capacity reloading container built for serious handloaders who process volume. Whether you're running a dedicated shotshell press or cycling through different powders and shot sizes in a single session, this universal large bottle gives you the storage and quick-swap convenience you need to keep your press fed without constant interruptions.

Built from clear polyethylene, the bottle holds 40 ounces of powder or shot—enough capacity to minimize refill stops during extended reloading runs. The design is straightforward: a screw cap for secure storage between sessions, and a plug cap that stays in place while you pour powder or shot directly into your press hopper. No need to remove the bottle each time you need to reload; just refill and keep working. The clear construction means you can see your powder or shot level at a glance, so you know when to prep the next charge before you run dry.

If you run a MEC reloading press—whether a 600 Jr., 650, Sizemaster, or any other model in the MEC line—this universal bottle threads right in. It's the practical solution for managing different shot sizes or switching between powders mid-session without fumbling with multiple containers or risking contamination. Pair it with the smaller 20 oz. capacity bottle if you want options for lighter loads or testing new powders without committing a full 40 oz. supply.
