Hi Tek bullet coating

Post by KennyA » 01 Jul 2017, 6:43 am

Hi,

I'm interested in trying to epoxy paint or powder coating my cast bullets.
I'm currently casting Lee 457-405 bullets

Does anyone have any experience with the Hi Tek product...?
Can it be purchased from an Australian supplier..?

Cheers and thanks in advance.

I just looked at http://castboolits.gunloads.com
There is a forum down the page called "Coatings and Alternatives"

A pro shooter i know powder coated his 6mm BR in Molybdenum Disulfide by tumbling in a homemade bit of pvc pipe rotating like a cement mixer

I powder coat cast bullets for my 308 with normal powder coating powder. I do this by shaking the bullets and powder in a plastic container then backing them.

It works great.

I.ve tried two different powder coats. One would not stick to the bullets at all and the other one does not coat even.
I have seen the YouTube vids were they use Harbour Frieght and Eastwood powers with very good results. These appear to only available in the US.

Just curious OP - what's your end goal with this? Are you having trouble with accuracy? Are you hoping to push them faster? Are you having measurable issues with excessive leading? Have you slugged your barrel? What rifle are you using? Sorry for the 20 questions...

Here is some reasons why I powder coat bullets.

You don't have to worry so much about the lead alloy hardness. You can push them faster easier. If the bullet isn't big enough for your gun your can make it bigger. No sticky lubricants. Once you have a bit of practice pretty quick and easy to do. Cheap and don't need to get any expensive equipment. And they you can get lots of cool colours!

In my opinion Hi Tek is the way to go versus powder coating. Hi Tek was developed here in Australia by Joe Ban. His contact details are...

You will need a little bit of equipment such as an oven you can maintain accurate temperatures with. The other stuff needed is basically what you already have.

If the coating is applied correctly (it's not rocket science) you will never have leading of bores unless you use very hot loads. Bores are very easy and quick to clean and the Hi Tek coating is very easy on bore wear due to its low friction and lubricating properties. I use Hi Tek coated handgun projectiles 95% of the time in 9mm and 45ACP. Will be doing some 303 rifle versions soon.

Of course those are valid reasons, so I take it these facts are true for you:

1. You push your rounds faster than plinking speeds (i.e. > ~1300fps)
2. You have a (slightly) incorrectly sized bullet for your actual bore diameter (meaning you need to gain that extra thou or two via coating)

If those facts are not true, couldn't you get away with naked lead combined with a simple pan lube? Food for thought...

I Googled the epoxy paint bullets are reading here, looks like a tonne of work compared to moly for much the same end result?

Why do you consider Hi-Tek to be better than PC though?
And where can we buy Hi-Tek?

Buy the Hi Tek direct from the maker Joe Ban. His phone # is above.

Many people prefer the powder coating because they've never tried Hi Tek. Hi Tek is faster to apply, less finicky to apply correctly. If you do low volumes of cast bullets either method will work but if you do any sort of volume Hi Tek is the way to go.

Just my opinion. I have no empirical evidence one is "better" than the other. All I know is I shoot several thousand Hi Tek coated bullets a month and end up with accuracy much better than my vision would allow, cleaning of barrels is easy, zero leading in bores.

Each to their own. If you are succeeding with PC then keep doing it.

How did you go with 303?
I think my barrel is a smidg large for the .312 185 grain lee cast I have. Coating may help. What load/velocity worked for you?

Cheers.

Do not have my sizing machine yet for the rifle bullets. It's leaving the U.S next week. My existing handgun bullet automated sizing machines can be adapted to rifle but because I do so many handgun bullets I don't want to cause my self the grief of changing setup to do a few hundred rifle bullets every now and again.

I ordered a Star Sizer (manual machine) without lubing facility. I have several dies (.311" and .312"). I'm also having a new mould made in a month when the CNC company is back at work. The mould will allow up to .315" diameter finished bullets somewhere between 170-185gr in weight.

I did try some .312" 184gr Hi-Tech coated bullets from a friend. He cast them from my material (virgin 92-6-2 from Northern Smelters Brisbane) I coated them 3 times and he sized them. Using my usual ADI 2206H powder I loaded cases with 24gr and they performed perfectly. Lighter recoil, no leading in my Lithgow No.1 MK111 which has excellent barrel bore. I did not have a chance to chrono so I don't know velocity. Accuracy seemed at least as good as the jacketed factory style rounds up to 100 metres. If I was to guess velocity it would have been about 1750fps or less. Remember these bullets have no gas checks and I do not intend using any ever.

There is always the concern about too little powder volume in the .303 case but I basically worked on the minimum 66% fill compared to the normal load I used with jacketed bullets. With those bullets I use 35-36gr of the same powder. There is also no reason you couldn't use handgun/shotgun powder to better fill the case...AP50N/APS450 with about 12gr which would produce an estimated 1500-1600fps.

Thanks for the info.
I think I'll give the process a go.

I Hitek coat, swaged pistol bullets, works well. But some say it increases barrel.wear. the jury is still out for me though. Works well on cast rifle bullets also.

Reduces barrel wear significantly over jacketed or plated bullets.

Can you verify this? I set up to Hitek because I thought it was what people wanted but the local pistol club is dead against it! I personally prefer Alox based lubes myself.
