HI-TEK do's and don'ts

[Moonman]

Michiganvet,

Between the Lanolin and the SWEDGING Die you just might have issues
with HI-TEK coatings.

Others have found that LUBES really cannot be cleaned off enough,
and any sizing before the first coat is applied interferes with adhesion.

[Ausglock]

What he said......

[leadman]

Yes, sizing burnishes the metal and there is nothing for the Hi-Tek to cling to. I know this from experience removing wax based lube from already sized boolits and then coating and shooting. I did have some minor success using a very strong alkali soap to etch the surface of the boolits but it was time consuming and not worth the effort.

Alkali cleaning of Lead is not recommended as it produces toxic solubilised Lead salt solutions which can be absorbed via skin and is requiring treatment to remove Lead prior to dumping.
Simply, do not use any lubricants when casting that would transfer onto cast alloys.
Then coating is easy and more successful.

Except for the HI-TEK Super 500 Mold release.

I stand corrected Ausglock.

This is what I use to calculate my mix, this may be helpful for some, so I'll share.

Simple stuff, but it takes the guess work out of it.

Nice. But a little extra catalyst will not hurt your coating.
My 5-1-7 mix is actually
50mls of coating
10 to 12 mls of catalyst
and about 75mls of acetone.
It depends on how quick I stop pouring.....

Your findings are correct and indicative on metal loading..
I am of the opinion that when coating in small ovens, especially if air circulation is not the best, the amount of projectiles into the oven, should be based on weight not number of projectiles.
Then, this will provide equal "mass loading" each time, and baking time should be relatively similar each time.
Theory is that 100 small calibre projectiles have less metal weigh as compared with 100 larger calibre projectiles that have much higher weigh of metal content.

I agree 100%. Use the exact same weight each time and not the bullet count. This will help with both coating, drying times, and baking time. Keep all of the variables the same!

BMac,

Your new link SHOWS that image, but I can't make it do anything.

Except for the HI-TEK Super 500 Mold release.

OK, what is this stuff?

[Moonman]

It's Super 500 "MOLD RELEASE".

Sprays on mold, causes bullets to fall out of the mold.

Available probably from WHOEVER you purchased your HI-TEK

coating supplies from, such as Bayou Bullets.

I just used some to break in a NEW Iron 9 MM Hardline Industries

115 gr 4 cavity, it drops some beautiful NO LUBE GROOVE projectiles.

How does HI-TEK hold up at rifle velocities?

I'm coating 45 and 10MM at present. My 10MM are about 1200fps without any issues. How fast can coated rifle bullets be pushed and does the increased barrel length make a difference?

Thanks

[Gateway Bullets]

This is what I tell my customers.

The coating has two categories, metallics and nonmetallics. The nonmetallics such as green, black, red are good to around 1300-1400fps. The metallics such as the red copper, gold, and others, have micronized metal in the coating and works to deflect the heat generated. They can be pushed as fast as you want!

Then I explain that I have a customer that runs black on his 300 blackout around 1800 without leading. He did have a little of the coating burn off the base when he used a hot powder. But I suspect the coating wasn't cured all the way.

I also have another customer that runs a Rossi lever 38 and he is running some 38-158 swc I coated for him in red copper. He reported that he is running them around 2400 fps without any problems and LOVES the coating!

I dont know if you have seen these results.
These were done in US some time ago and posted.
Below are results.
Hope it answers some of your questions.


All the boolits were coated with the Red Copper Hi-Tek.

Please check your numbers. 2400 fps out of a Rossi .38????

There are reports of 3000+ fps with the coating but accuracy is poor - at least so far.

Don Verna

The number is correct as he reports it! The first number he stated was for the gold coating at just over 1800fps. Then he requested the red copper so he could push it to 2400fps. He returned and stated that he ran it in the load for the faster speed and reported total success and no leading.

I believe it was the Rossi R92.

I don't understand your negativity with this coating. People report success and velocities achieved and you don't seem accept it. Why? Have you tried the coating? Had a bad experience with it?

Not trying to bash or stir the pot with you, I'm just trying to understand!

[KYShooter73]

I can't say its a do or a don't, but I mix my Hi-Tek black in a soy sauce bottle. Works great for mixing and dispensing. Just be very careful what you put on your rice. They are not interchangeable!
