Cartridge History
The 10.75×68 is a historic continental big-bore cartridge associated with Mauser-pattern sporting rifles built for large and dangerous game.
Common Rifle Types and Platforms
- Historic Mauser and Mauser-pattern sporting rifles chambered for 10.75×68
- Continental custom rifles with a positively verified chamber
Compatibility warning: Historic sporting rifles may have been altered, rebarreled, or marked under older naming conventions. Verify the exact chamber, bore, and loading-tool compatibility before ordering components.
Legacy
The cartridge offered large-bore performance in a magazine rifle of practical size. Today, surviving rifles are specialist collector and hunting arms requiring scarce components.
Did You Know?
Older rifles may vary in bore, throat, and chamber dimensions. Confirm the individual rifle and do not rely solely on the alternate '.423 Mauser' description.

Frequently Asked Questions
Is this loaded ammunition?
No. This listing is for new, unprimed brass cartridge cases only.
Will this brass fit every rifle with a similar caliber marking?
No. Match the complete cartridge designation to the exact chamber. Similar metric or imperial names may identify different cartridges.

Inspect every case. Sizing or expanding may be appropriate for the firearm, chamber, bullet, and loading tools.
Why is this brass produced intermittently?
Demand is specialized, so Bertram generally manufactures these cases in scheduled batches rather than continuously.
