I just got a Hornady tumbler and Frankford Arsenal corn cob media. I put 30 cases of 50 BMG in the tumbler and after three hours the cases look pretty clean and shiny but the necks still have a lot of crud on them. I let the tumber go for three hours straight with four teaspoons of brass polishing media.
Am I doing something wrong? Should i use walnut instead? Also during resizing holy cow, deprimes
just fine but during the portion of pulling the case out out of the die it is like a death sentence. Should I clean the inner portion of the neck to smoothen the extraction of the case after it has been deprimed? All inputs appreciated.
