Send us a brand new or fired case that has not been sized or de-primed for the most accuracy!
Please send all brass cases to us at:
Copper Creek Cartridge Co.
2448 Hollandsworth Rd
Rosebud, MO 63091
Be sure to include your name and phone number, and/or an order number!
Please ship your fired case in a box for the best results. The USPS is tough on packages and we have received lots of brass that has been smashed or crushed during transit. Using only an envelope will most likely result in a lost piece of brass.
We ask that all modified cases are sent to us within 30 days of ordering, after 60 days your order will be cancelled. No refunds will be offered to orders not completed in this time frame.
Turnaround is one business day once the case is received.
