Hi all,
I reloaded some .357 magnum. The brass is headstamped "A USA". It was given to me by a friend who fired it once. While inspecting I found a case with a horizontal axial "cut" about a quarter inch above the rim. This cut didn't circumvent the whole casing. only on one face. I scrapped that piece and continued to reload. After the process, I found a loaded round with the same imperfection. I have included a photo below.
My question is. What could this be? Is it defective? Should it be discarded? (I am compelled to do this unless I receive overwhelming support to the contrary.) Should I scrap the whole batch?
If it is relevant the rounds are loaded with 6.0 grains of Unique so not very hot.
