I have a quart ziploc bag of 7x57 brass you can have. I don't know how many that isn probably over 100. It is old military surplus. Bullets have been pulled, powder dumped, but it still has the original primers. Most of it is headstamped 1920. I would recommend annealing before use. Got this in a large box of misc. stuff at an estate sell. If you want it you can have it for shipping costs.
