Has anyone documented the temps at which the phase change of the various maker's actions takes place. You have to know this to anneal, and also if you are recoloring, you daren't go above the decalescence temp of the core of the action otherwise you have a piece of glass. The common wisdom is to stay under 1325 but Brownell's actually recommends 1400 in their Case Coloring instructions. Brownells also says to temper to 350F but that's way too low to make any difference to the hardness.
