cam. You probaably need a different example. According to QL, 28gr of Varget with the 107SMK gives about 50000psi and 95% case fill in the 6mmBR but 75000psi and 114% case fill in the 6PPC which strikes me as unlikely just for the case fill. I routinely run 29.5gr of Varget in my 6mmBR with the 107SMK and the other bullets in that weight class but I doubt that many are jamming that much powder into a PPC case, at least according to QL.
