Today, I had enough 357 magnum brass that needed depriming and cleaning, so I decided to use a formula gained from the 'net.
According to the recipe I copied, ~ 1/2 gallon of hot water, dump in 1 Tablespoon of Lemishine, and 2-3 drops of Dawn. (Does the brand make a difference?) Shook it, waited about 20 minutes, the outsides were really shiny, and the primer pockets were fairly clean, too...better than with a vibratory tumbler.
I figured if one Tbsp. was good, more would be better, so I added about 3/4 Tbsp. more of Lemishine. Agitated it several times in about 15 minutes, rinsed, and spread on a towel on the driveway to dry. Not much change...the outsides were very shiny, the primer pockets good, and the interiors looked somewhat improved, but nothing like the examples I have seen, which show the interiors in nearly pristine condition. Would more be better? I also have some straight citric acid...would that be better? Should I have let them percolate for several hours or maybe overnight?
Next: Is uniforming the flash hole, just removing the jagged edges left from punching the primer's flash hole worth the effort for more consistent reloads, or is it just more ballistic proctology?
And finally: I have one of the dessicant canisters that I keep in my primer storage box...about the size of a 3"X 5" card, with instructions to for "recharging" the crystals by baking it in the oven at 300 degrees for 3 hours! Man, that would heat up the house, and the Spousal Unit would not be happy! We are having 100 degree days, so would leaving it outside in direct sunshine reactivate the crystals, do think?
Just more of the many pleasures of Reloading, eh?
