How to Prepare Brass for Processing

Before sending cases, contact Wissota Brass to confirm the caliber, requested package and return arrangements.

  1. Sort and label: Keep calibers separate and label each container with your name and the caliber. Note any requested headstamps or primer-pocket preferences.
  2. Confirm what you are sending: Tell us the approximate quantity and condition, including whether primers remain in the cases. Do not include loaded ammunition or loose primers.
  3. Pack securely: Use a sturdy box with a strong inner liner, secure the seams and include your contact details and agreed processing request in each package.
  4. Arrange shipping: Confirm the shipping address, carrier requirements and return shipping with us before dispatch.

Understanding Weight Estimates

Case weights vary with headstamp, caliber, primer status and condition. Use the weight calculator for approximate counts and net brass weight. Packaging adds to shipping weight; inventory and final quantities are confirmed separately.
