5.56/223 Mixed Range Brass. Three buckets of different weights. Some I've shot myself. Looks like it should be brass and not steel casing. I threw out any split cases. I didn't segregate it by 5.56 or 223. There may be some nickel plated cases mixed in with them.
You are purchasing the brass by the bucket weight. I have no idea how many rounds are in each bucket. It is as the picture shows...Text me if you are interested at the listed pricing.....
