I have a tumbler from Midway Shooting Supplies and it has
cleaned and polished countless thousands of rifle and pistol
brass over the years. Maybe you have overloaded them. There is
a tumbler made by Dillion Precision. It has a great guarantee,
and many of my shooting buddies love them. If anyone is
interested, E-mail me off line and I’ll get their 800 number.
