Check and clean your brass in SASS Wire Posted 8 hours ago I take a layered approach. When I pick up my brass at the ULT it gets a good shake. If it makes that tinny sound, the split brass is located and discarded. After cleaning, brass gets a visual inspection before going into the hopper. While reloading, at station 4, I will generally notice split brass because the bullet will seat too deep when I press it into the case mouth. When at the LT, all brass, and primers, get another look. So far after just over 10 years of CAS only one split has made it through to a match.
