I had an "ah, ha" kind of moment tonight. I tried graphite in Rem 700 trigger group once and it just made mess. Now I keep that one dry except for using Ronsonol lighter fluid to flush it out (it dries with a light varnish). Anway, I had tried Tetralube on Handi hinge and Rem Oil on most moving parts. The problem is that Rem Oil collects soot and dust. I will try the Hornady first as I know how well it works on brass.
