Winchester Ammo WSC500SWU Unprimed Cases500 S&W Mag Handgun Brass 50 Per Bag

If you're setting up a .500 S&W Magnum handgun reloading bench, Winchester unprimed brass cases give you a clean, consistent foundation for building your own loads. The Winchester Ammo WSC500SWU comes as factory-new, unprimed cases—50 per bag—ready for your press. Winchester manufactures its own brass from raw material through to the finished product, which means tighter tolerances and a more uniform product than brass sourced from multiple suppliers. That consistency matters when you're working up loads for a powerful magnum round.

Each bag of Winchester .500 S&W Mag brass comes from the same production lot, so you'll get matching dimensions and material properties across all 50 cases. That lot-to-lot consistency helps you dial in your loads and reduces variables when you're developing ammunition. The cases are built to handle the pressures and abuse of multiple reloading cycles, so you can reload them confidently as long as they stay in good condition.

Serious handloaders who shoot .500 S&W Mag revolvers appreciate quality unprimed brass because it lets you control every variable in the cartridge—bullet, powder, primer, and charge weight. Winchester's in-house manufacturing and tight quality control mean you're not guessing about case dimensions or wall thickness from bag to bag. For hunters or handgun enthusiasts loading magnum revolver ammo, this is a straightforward, no-frills choice.

Frequently Asked Questions

What does "unprimed" mean for reloading brass?

Unprimed brass cases have no primer installed in the pocket. You'll add the primer yourself during the reloading process using your press and a primer tool.

Can I reload these Winchester cases multiple times?

Yes. Winchester brass is designed to withstand the stresses of multiple load-fire-reload cycles, so you can reuse these cases as long as they remain in serviceable condition and show no signs of damage or excessive wear.

Why does the production lot matter for reloading?

All 50 cases in this bag come from the same production lot, which means they'll have matching dimensions, wall thickness, and material properties. That consistency helps your loads perform more uniformly and makes it easier to develop accurate loads.

Is this brass suitable for .500 S&W Magnum revolvers?

Yes. This is .500 S&W Mag brass, designed for handguns chambered in that caliber.
