simple Hi-Tek coating

I squirted some Zombie Green in the bowl while coating with TMG Gold.

Thanks for the advise Joe, i'll be sure to give this a go next time i'm processing range scrap. I have easy access to shavings, i may need to start keeping the ones i generate with my lathe and metal cutting saw

Petander - those look awesome!

Petander you have just invented Aussie colours Green and Gold.. very nice...

I done a first coat with Candy Apple Red and a second coat with Liquid Black and liked the way it came out, I called it Black Apple.
Sometimes mixing colors look nice and sometimes not but always shoot fine.

I've gotta say, that's pretty cool, and I normally don't really care for green!

So i bit the bullet and bought 500 Grams of Black K15. At what velocities do you go from single coat to double coat? My loads are .32 88 grain BBWC @ 700 fps, .38 144 grain BBWC @ 800 fps, .357 125 grain TC @ 1300 fps, 38 Super 125 grain TC @ 1350 fps, .45 200 grain SWC @ 850 fps , .70 1800 grain TC @ 1100 fps. Most are Lee Tumble lube apart from the 70 cal. Any pointers greatly appreciated

Always do 2 coats. K15 covers very well. Overbaking is no problem as black is black. I have never had good results with coated tumble lube bullets.

Accuracy or leading or both

Yes! And can you believe,I just read that this has been invented somewhere in Australia already! Such a coinsidence.

Both. The 228gn 45 tumbled badly.
The 9mm TL bullets leaded like buggery.
Go buy some decent molds from Tom @ accurate molds in the US. his molds are first rate.

[M.A.D]

Oh he does do good molds. Did my 1800 grain Hollowpoint

I had the same issue with the 124gr tc tumble lube bullet in 9mm until I slowed them way down then they where a great plinking load with about .22lr recoil but I’ve since moved to better bullet designs that allow me to load to make minor power factor.

I am glad this heads up on the tumble lube moulds was posted, I very near purchased one thinking it would be a good bullet to coat and use. Regards Stephen

Any conjecture as to why these particular bullets lead and/or are inaccurate? And you had leading using these with Hi-tech coating? How about with powder coat?

Thanks,

[Ausglock]

I think it has a lot to do with the poor bearing surface. All the little grooves seem to cause the bearing surface to strip when engaging the rifling. especially when pushed fast in 9mm or 38Super.
The 45 was just very poor accuracy and tumbling.

I believe I have read some place that they shot well with powder coat, but I have seen some pics of them powder coated and it seems to fill the little grooves in them. I think Ausglock is right about bad bearing surface being the problem, not even Hi-Tek can fix a bad bullet design it seems. Regards Stephen

Hmmm... I have one of these molds that I've never used. Maybe I will just machine the lube bands out of the mold and use it as a "coated boolit only" mold.

Thanks for the answers!

I did this with a Lyman 156gr steel mould and it made a great 170 gr bullet after lube grooves removed. Regards Stephen

[Vettepilot]

Sounds like a plan then.

Not a bad idea, I think i will do it myself
