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.
