Just received my media, tumbler, case trimmer and dies. Cleaned about 250 cases and grabbed 5 to get the rcbs fl sizing die setup. Here's the photos... Pictures aren't great but the shoulders seem to be buckling/denting. I'm using rcbs lube on the lube pad. It's cold in the garage so the lube comes out like syrup. Too much lube? Too little? Directions said something about vent holes, but when I cleaned it I didn't notice any. Any help is appreciated.
