I have a bag of 100 308 Win brass that has been cleaned and polished but not sized. It is once fired. I would like to trade for 7x57 Mauser brass. I would be willing to purchase the 7x57 brass also. I can be contacted by PM, email- dlallder88yahoo.com, or home phone 903-855-0441. I am deer hunting nearly every day so may be be hard to catch. Thanks Daniel Allder
