One of the tricks I used back then was to mix some sawdust--or "sanding dust"--from the stock I was working on with the epoxy, which gave the mix somebody. Probably read about that somewhere.
But one thing I have discovered in the years since is that even 5-minute epoxies can work for "skim bedding" some stocks--as long as the inletting is already pretty close. In those sorts of instances there doesn't need to be much structural strength to the epoxy itself, like in Acra-Glas Gel or Steel Bed. Instead it just fills in slight imperfections in contact between stock and action.
