Hi all, while new here, not new to shooting, reloading and annealing.
I have been utilizing this method for two years now. I have mostly used it to anneal my 50 BMG Match Brass (I compete in FCSA Matches), and it has given me very good results.
As far as the process, I put an old baking sheet/pan under my Lee Pot, to prevent anything from dripping on my bench when I remove the cases. After removing case from salt bath I immediately drop the case into a 5 Gal bucket filled about half way with cold tap water (make sure bucket is on the floor to prevent ANY possibility of splashing water into salts). When finished, I put the cases into a Frankford Arsenal Dehydrator for drying.
I have found that the Lee Pot Temp controller, left a lot to be desired, when trying to maintain constant temps. The PIT Controller mentioned above, cured that issue.
When finished annealing, turn off your pot, and let the salts cool and harden. Then dump the hardened salt "puck" back into the original salt container and tightly close the lid. This prevents any possibility of moisture absorbing into the salts.
Lastly, NEVER allow the salt temp to exceed 590°C. It will produce harmful vapors. As long as you keep it below this temp (I anneal at 560°C) you will not experience any fumes.
Note: I've found that if I put just a little bit of Lemishine into the water, the cases come out, with no appearance of the annealing coloration. I like shiny brass..lol.
