BoydAllen said:Am I going to invest in a tumbler and some stainless cleaning media on the off chance that it might gain me some accuracy? No, because I have no reason to believe that it will, and the equipment is not cheap.
On the other hand, if someone furnishes definitive proof that my thin necked (.0086) 6PPC cases will produce smaller groups after something different is done to them, that would be a different matter.

You might rethink the .0086" dimension and do some testing yourself. I know I am.
