The other thing Dale, is that you are spraying them.
That removes a heap of the mechanical problems
For this excercise, spraying is out the window.
and with that goes a few very worthwhile powders that should be treated spray only.
in my last string of testing, two powders rose to the top of the heap. All Powder Paints Arctic Cat Green, and their Teflon Slip Black.
Both have properties that helped me gain another 200 FPS without coating failure.
Green will work with shake and bake, Black needs to be the full coat the first time.
it's thermal cure, rather than thermal set, and makes an astonishing release layer.
once cured, adhesion of subsequent layers is difficult or impossible.
Check your state laws before use of it, it is legal in most states, but not all, even some that kinda surprised me.
Teflon coat is not limited to bullets ...
I did the raceways, barrel, guide rod, and barrel bushing of my 1911 in this stuff, refit the parts and ran it bone dry of grease or oil for 2k rounds.
its accuracy and performance were much improved.
that old war horse spent the day showing an HK USP, Sig P220, Glock, and S&W M&P how it was done, so it remains worth having even if you cant legally use it on bullets.
one shot gun permalube.
I love this stuff like a fat kid loves cake.
another thing I've played with was a bullet repair method using the piglet coating method.
I see this one a lot.
someone who does not cast, buys a box of hardcast that leads up his gun.
He asks for help and hears "Lube and size correctly" as the advise.
Sorry man, you can't make them bigger with wax and a size die.
At the end of the day, this individual will have a big old box of undersized useless, a gun that won't have em, and a half bottle of aspirin headache from being inundated with advise that won't work.
The fix ....
dump them in an old pot, fill with water, and bring to a rolling boil.
Let cool and skim off the lube.
Add a little vinegar, and return to a boil.
remove from heat and immediately dump the pot out onto a screen.
let em dry.
coat using the Piglet method, where the powder is mixed with acetone, and tumbled till the solvent has evaporated.
Bake and repeat.
yeah, it works.
Might not be as good as properly born coated cast, but it does fix a box of mistakes.
Try it to confirm as you wish. We finally have a solution to offer.
Now if I can just get the old guard to embrace, at least this, as the long needed roll of ducktape we've been looking for, something great would have been accomplished.
