Description
Anyone who runs a MEC shotshell press knows how handy it is to have a spare bottle ready to go. The MEC Outdoors 8042 is the magnum, large-capacity version that holds roughly 40 ounces of shot or smokeless powder in a clear, high-impact plastic body that lets you see exactly how much you have left. It stands about 12 inches tall and is a universal, multi-caliber accessory, so it isn't locked to any single gauge and fits across the MEC reloader line.
What Sets the 8042 Magnum Bottle Apart
The magnum size runs a slightly wider neck than the standard bottle, which helps shot and powder feed smoothly down into the press hopper instead of bridging up. It ships with a red top pour plug for controlled dispensing and a white threaded bottom cap that seals everything up tight between sessions. That two-cap setup is the reason reloaders like keeping a few of these on the bench.
Why Reloaders Keep Extra 8042 Bottles on Hand
If you shoot more than one shot size or run different powders, the fastest way to cut down changeover time is to keep each one in its own labeled bottle. Pop the full bottle off, cap it, grab the next, and you're back in business in a couple minutes with no spills and no guesswork. It beats glass jars too, since hard plastic won't shatter and it stands up to the solvents and residue that live around reloading gear.
Storing Shot and Powder Safely
Smokeless powder should always live in a cool, dry spot away from sparks, heat, and open flame, and well out of reach of kids. This bottle is built exactly for that kind of storage, giving you a secure, sealed container that won't trap dangerous pressure. Keep each one labeled and you'll always know what's inside at a glance.

Frequently Asked Questions
What size is the MEC 8042 Magnum bottle and how much does it hold?
This is the large, magnum-size bottle in the MEC lineup, standing about 12 inches tall. It holds roughly 40 ounces of shot or smokeless powder, which makes it a good fit for high-volume reloading sessions. The clear body lets you keep an eye on your level without pulling it off the press.
Will the 8042 bottle fit my MEC reloader?
Yes. The 8042 is a universal, multi-caliber accessory that fits across the MEC reloader line, so it isn't tied to a specific gauge or cartridge. It works on any MEC shotshell loader or powder setup that accepts the magnum bottle form factor.
Can I use the MEC magnum bottle for both shot and powder?
You can. It's designed to safely hold either loose shotshell shot or smokeless powder. The slightly wider magnum neck helps shot flow smoothly into the hopper, and the white threaded bottom cap seals contents for storage between sessions.
What caps come with the 8042 bottle?
Each bottle ships with a red top pour plug for controlled dispensing and refilling, plus a white threaded bottom cap for sealing it up when it's off the press. That combination is why a lot of folks keep several on hand, each labeled with a different shot size or powder to speed up changeovers.
