Why Choose Bertram .43 Spanish Brass?
- New-production brass for a historic or obsolete cartridge
- Manufactured by Bertram in Australia
- Provides an alternative to scarce, aged, or altered original cases
- Imported and supported in the United States by Desert Tech Munitions
Cartridge History
The .43 Spanish is associated with Remington Rolling Block military and sporting rifles supplied to Spain and a number of Latin American users during the late nineteenth century.
Rolling Block rifles were produced and later altered in several closely related .42- and .43-caliber chamberings. For that reason, rifle identity alone is not sufficient proof that a chamber is .43 Spanish.
Historical Firearms
- Remington Spanish Model Rolling Block rifles
- Military and sporting Rolling Block rifles verified as .43 Spanish
- Later commercial or surplus rifles that retain a confirmed .43 Spanish chamber
Compatibility warning: Similar rifle models and similar cartridge names do not establish interchangeability. Verify the precise chambering marked or measured on the firearm.
Collector Notes
The .43 Spanish and .43 Egyptian are distinct cartridges. Specialist Remington researchers document that surviving Rolling Blocks may have been rechambered or misidentified during their service and surplus lives. A chamber cast is the safest way to resolve an unmarked or uncertain rifle.

Frequently Asked Questions
Is this loaded ammunition?
No. This listing is for new, unprimed brass cartridge cases only.
Can this brass be reloaded?
Yes. Case life depends on chamber dimensions, loading pressure, preparation, sizing practices, and inspection between loadings.
Should new cases be sized before loading?
Inspect every case. Sizing or expanding may be appropriate to establish correct shape and neck tension for the specific chamber and loading tools.
Why is this brass produced intermittently?
Demand for obsolete cartridges is specialized, so production is normally scheduled in batches rather than maintained continuously.
Is .43 Spanish the same as .43 Egyptian?
No. They are distinct cartridges with materially different case dimensions.
How can I confirm an unmarked Rolling Block?
Have a qualified gunsmith inspect the rifle and make an accurate chamber cast. Historic model descriptions and external markings can be misleading after military and surplus alterations.
