Several post here about annealing, so sorry if this is redundant. A few guys were mentioning using hot sand or bead blasting media in a pot, so i got an idea for using the same method, but with a media that is denser and holds heat better. Went to Harbor Freight and picked up a pound of their spark plug cleaning media. VERY heavy for the volume. Seemed to work well and about 5 seconds per case at 700 degrees is all it took to anneal the cases (using 270 winchesters which will shortly become 7mm mausers).
Anyway, thought I'd pass this along.
