Hi-Teck Coating

Fiver,
Did you ever do the high teck coating that you were thinking about over on CB?
Did you try it on rifle bullets?
Was thinking about doing it but haven't found a supplier for one and enough info
for my old brain to understand.

I've used it on pistol and tried on rifle. PC is soo much easier (& cheaper) it sits on the shelf. It does work good if applied correctly.

Brad used to use it also, but I think he's converted to powder coat shaking method.

powder is the way to go over the two and maybe 3 [coats] cooking of the Hi-Tek.

I ain't made it to trying powder coat over the jacket bullets yet.
but I do know that brass and copper will take powder coating, that much I have tried.
and I have had some decent success in swaging coated lead bullets.
I'm still working on it, I guess I just haven't focused on the project enough to complete it.

Hi-Tek is a faster, easier application. Need for 2 bake cycles slows the process. No standing up bullets is a plus.
PC is slower to apply in bulk. I do mass bakes with no standing them up.
I have had far better results with PC thus far. I attribute it mostly to the thicker coating.
I haven’t used my Hi-tek in some time but PC lots of stuff currently.

My 9mm is very happy with PC, never had good results with HT. Same bullet, size, and load. That was all I needed to know.

Who supplies the Hi-Tek materials?
Is there a American supplier?
What does a starter set cost or an estimate of cost?

you basically buy the powder and supply your own acetone.
stick with the reds [golds are okay] for the best coverage.
simple procedure but you do have to pay attention, when the solution becomes 'sticky' you stop shaking and pour everything out of the cup.
your building up layers of cross linked polymers, just like when painting something get the first thin smooth coat laid down and build on it.

Mine was a 2 part liquid that was diluted with acetone. Simple to apply. Like PC, less is more. Heavy applications don’t dry as well and if baked while even slightly damp you get poor adhesion.

I prefer the application method of Hi-Tek but the coating is thin and just doesn’t do as well for me.

Brad,
Did you try it on rifle bullets?
Were you able to run them at jacketed velocity?
Or were you restricted to cast velocity?

I used it on a few rifle bullets but not over 1600 FPS. It worked OK but I really think PC is far superior.
I never tried it at over 2000 FPS.no idea how it would work in that realm?

I think the thicker coating of PC is the difference. It does better job of preventing gas leakage at higher pressures. I think it is also more resistant to scraping off.

I have some 30-30 bullets I coated with Hi-Tek but when sizing them in a push thru sizer I have issues with scraping of the coating in a few spots. Bare spots would be a problem so I never fired them.

Dan of Mountain molds did a very high-velocity test comparing HT and PC in a 6mm BR and found the coatings were similar. He wrote about it extensively on his forum.

I started with green liquid on pistols, worked fine. Got gold powder for rifle, kinda worked. I was doing small batches & had some trouble with adhesion.

Thanks all for your input!
Lets me know that at my age it is not something to try.
I mean that in a good way.
With my wifes health and my age was kinda looking for something simple to
keep me busy so I do not spend too much time worrying about something I and God cannot change.
Thanks again
