Sorry if what I'm about to ask has been hashed before. I did a search and didn't come up w/ much. My question is how to you feel about buying once fired brass (specifically 9mm & 45 auto). It certainly would help keep the cost down especially when you never seem to find 100% of the brass fired out of an auto. Cheyenne Brass currently has 9mm listed for $36.00 on the 1000. 45 auto is $62.00 on the 1000. Has anybody used these guys?
