What “test methodology” are you referring to? Let me be as clear as I possibly can here: at no point did I make any claim whatsoever regarding graphite yielding an increase in accuracy. None whatsoever! I do, however, firmly believe that tumbled round balls are more accurate than their untumbled counterparts. This belief stems from my own experience as well as countless other member reports.
Graphene is used as a corrosion inhibitor in many applications, so I see no reason why it shouldn’t offer protection against the oxidation of lead round balls; however, I don’t claim to be an expert, and I never professed to invent the process of tumbling round balls in graphite. As I’ve only been doing it for a couple weeks now, how could I possibly make any assertions about its long term viability in that regard?
I’ve already rescinded my statement insofar as patch and ball is concerned in a former post. I was misled.
