word is, and rumor has it that what you have will work, however the crossman black seems to lead the pack in static generation.
One guy was starting to turn out some very promising results tumbling the bullets while hot.
Still, all roads lead to an ES gun.
I have a Lee 208 WC mold myself.
these things never did well above 1000 FPS. they start to tumble, which is an issue no coating can solve.
It will, however, make them a joy to load.
Some things beg to be pushed, others, not so much.
Wad Cutters ... not so much.
My lab, as it were, is branching off into two different directions.
Question one, is with the right coating and a good hard alloy, just how fast can we go? that'll be a rifle only experiment. No handgun can get to where the HF powder and WW lead combo made it to.
next question, is just how soft can we go while maintaining about a 1500 - 1600 FPS limit, without failure.
Soft lead anything at magnum levels will make for an expanding bullet HP or not.
If it can make it on merit of the coating ... that's a significant win.
fast production, as one would like in blasting ammo, with an upgrade and no real added expense.
