Lyman Single Cavity 12Ga Foster Mould 475 Gr

The Lyman Single Cavity 12Ga Foster Mould is a dedicated casting mould for reloaders who want to produce consistent 475-grain shotgun slugs. If you handload 12-gauge ammunition and prefer the control and cost savings of casting your own projectiles, this single-cavity Foster-profile mould gives you a straightforward, repeatable way to pour slugs at the bench. Foster slugs remain one of the most popular and effective designs for hunting and sport shooting, and casting them yourself eliminates the guesswork of buying factory slugs while letting you fine-tune your loads.

Lyman has been in the casting game long enough to know what works. Their single-cavity design means you're pouring one slug at a time—slower than a multi-cavity, sure, but you get excellent dimensional consistency and easier quality control with each cavity. The mould handles the specific weight and profile of a 475-grain Foster slug, so you know what you're getting every time you open it.

Casting shotgun slugs requires a lead source, a quality casting pot, and patience, but the payoff is ammunition tailored to your barrel and your needs. Whether you're reloading for hunting, patterning loads, or just tired of factory price tags, this mould is a core piece of the casting setup.

Key Features

• Single-cavity design for consistent slug-to-slug uniformity

Frequently Asked Questions

What does a single-cavity mould mean for my casting workflow?

A single-cavity mould pours one slug at a time. It takes longer per round than a multi-cavity mould, but you get tighter dimensional control and easier inspection of each casting. It's ideal for reloaders who value consistency and don't mind a slower pace.

Will this mould work for 12-gauge hunting loads?

Yes. The 475-grain Foster slug is a time-tested design for hunting applications. As long as your 12-gauge barrel and load data support this weight and profile, you can cast slugs for your hunting ammunition.

What equipment do I need to use this mould?

Beyond the mould itself, you'll need a lead source, a casting pot (electric lead furnace or stovetop), casting tools (ladle or injector), and proper ventilation. You'll also need 12-gauge reloading equipment—press, dies, primers, powder, and wads—to complete the loaded rounds.

Can I cast different weights with this mould?

This mould is designed specifically for 475-grain slugs. It is not adjustable for different weights. If you need a different grain weight, you would need a separate mould.
