simple Hi-Tek coating

[HI-TEK]

Just wanted to pop in and say how awesome K15 black has been for me!
I have coated everything from 22-250 (reduced loads round 2000 fps) to 30 Mauser, to 45acp to 375 H&H (Full magnum loads gas checked) and have never had any leading, or residue in the barrel.
Best part is I don't have to worry about over baking it, it just stays black.
Put it in the oven at 200 C and cook it till it passes the wipe test. Don't worry about over baking it.

Still never could get the Blue to work out, always came out green.

How are you doing Warhead.
Thanks for your post. I am glad you have had great success. The K-15 is a very slick coating, and tough as nails. Commercial casters here, also like the stuff.
With your gas checked alloy, what is alloy hardness that you used at 2000ft/sec?
The beauty of these coatings is that once heat set, over baking simply improves final film, but colour suffers badly with over bake.
Tests were done to see just what happens with baking for long periods. After 5 days at 200C although green went Black, it shot without any problems and was accurate.

Actual hardness I couldn't tell you as I don't have a hardness tester, it was a 50/50 mix of range scrap and Lino velocity were around 2550 FPS accuracy was good for the rifle I was using, about 2 1/2 inches at 100 yrds for a 5 shot group.

Also Happy new year!!

I really like to Tanned overbaked version. The dark Brown is also very nice. How do they look in sunlight?
Can you see any Glitter through that dark coating?
Just wondering what cooking times/details were done, to get each colour change?

Yes you can see some glitter in the dark ones. These colors are so hard to photograph with artificial light.

I first got the Lime Greenish tint by accidentally overbaking 30 cal bullets a little. Tan Gold comes next, then it slowly turns to Black Cherry,sort of.

There may actually be some sunlight outside right now but -20°C...

probably the gunmetal..

Yep, but it's sold as gunmetal, not blue. Warhead, increase your bake temp to about 235*C, same time, and it should change from green to something else.

No, it was clear and I mixed blue food coloring into it!!!!





Some 535 gain Lymans coated in K15 black, and a H&G 68BB coated in the dark blue that is a dark green in person.

Blue is a real tough color for Joe and Hi Tek. He has been working on it for a while. The closest I have used is the Dark Blue. But it is so dark that unless you have it in bright sun light it looks black. I think he is still looking for a formulation that will produce a true blue (pun intended).

For your true blue pun I recommend you for honorary Australian First Class.

Thanks Stephen.
Australia is one of the top five places I've always wanted to visit in the world.
