Lee Shotgun Slug Mould (Includes Handles) - 7/8 oz. .545" Length
$41.99
The Lee Shotgun Slug Mould is a dedicated casting tool for handloaders who want to produce consistent, quality slugs without the cost of factory ammunition. This 7/8 oz. mould casts slugs with a .681" diameter and .545" length, sized for use in rifled shotgun barrels. If you reload shotgun shells and want to control your components from powder charge to projectile, casting your own slugs gives you that capability—and Lee's mould makes the process accessible and repeatable.
Lee builds this mould from aluminum, a choice that matters in the casting shop. Aluminum heats and cools faster than iron or steel moulds, which means shorter cycle times and less waiting between casts. It's also lighter, reducing hand and arm fatigue during longer casting sessions. The mould block halves are CNC-machined to tight tolerances, promoting rounder, more consistently sized slugs—something you'll notice in shot-to-shot performance and ease of loading into your shells.
The mould includes a drive key feature designed to impart a positive spin to slugs in rifled barrels, which can influence downrange accuracy. The package comes with sprue plate handles, making setup and extraction straightforward, and includes instruction with suggested loads to get you started safely. For the slug reloader who values economy and control, this Lee mould is a practical investment.

Frequently Asked Questions
What's included with this mould?
The mould comes with sprue plate handles and instruction that includes suggested loads. You'll have everything needed to begin casting right out of the box.
What gauge shotguns will these slugs work in?
These 7/8 oz. slugs are sized for rifled shotgun barrels. Verify your shotgun's bore and choke compatibility before casting, as specifications can vary by manufacturer and model.
Why does the mould have a drive key feature?
The drive key imparts a positive spin to the slug when fired through a rifled barrel, which can improve accuracy and performance downrange.
Is aluminum a good choice for a casting mould?
Yes. Aluminum heats and cools faster than iron or steel, allowing quicker casting cycles and less fatigue during extended sessions. The CNC-machined block halves also promote consistent slug size and roundness cast-to-cast.
