Harris never said not to use fillers with any of the common rifle powders.
Well, turn it on its head, what powders does he say you SHOULD use fillers for?
So far we have no filler for Red Dot, nothing said about others.
I believe he also said that 2400 was not very position sensitive but I no longer have his articles to check that. I did pretty well with 2400 when I was tinkering with cast bullets. I didn't have any Red Dot, but 700X produced good plinking loads.
Ross Seyfried had some interesting ideas on fillers but with straight case Nitro For Black express rifle loads.
