simple Hi-Tek coating

[Shotgundrums]

So now that I've found the perfect time/heat crevice with this oven (11:00 @390-who knows if that's what it really is) would this also be ideal for my other bullets (larger) with the exception to quantity? Small:more, large:fewer? And could I stick with this for other colors out there like red copper/gold? Thanks all, and all my Australian heros

How long you leaving them after coating to when you bake them?

till they are dry to the touch. 3 to 5 minutes.

That's def part of it. Trev recommend 30 mins. I let mine dry for 20-30 as well. To achieve a shinier coat dump the bullets out before they get tacky in the bucket. Swirl until thinly-lightly coated-dump...
Also, well circulated heat is important. My first oven didn't have a fan and while the coating cooked and cured (ok), the finish was matte-like. I hated this so bought a new oven.

Not long enough. a full 10 minutes at the least is needed. And then warm them with a hair drier before placing in the oven. I like 30 minutes and this gives no problems. There are no shortcuts. Do the right thing and all will be fine.

RTFM..

thanks for the info guys i will report back with my results

Alright, I've skimmed this mile-long thread twice and still have a few rather important questions.

1. What happens if this coating is overheated, say into the 450F (230C) range?
2. At what temperature do boolits lose their heat-treatment from water-dropping?
3. Does the hot coating hold up to water-quenching?

For rifle boolits I'd need to be able to bump the hardness back up.

DanderDude - interesting chart. Do you have known As in your alloy? Leadman & I have made some attempts to get the BHN back up - I've never run the temp so high, even with naked CBs. I have the dark green and have not let it get much above 410F (air temp). WD has not hurt the coating that I can tell - still passes the smash test. Leadmans trick has been to cook it quickly (get the coating to cure) then drop back to 350F or so, I only do this on the last cycle. I've converted my oven to PID controlled so I can run a curve like yours on my alloy, task to be done this fall. Loading ammo today to shoot tomorrow.

I am looking at the ranch dog mold buy, what mold would be best with hi tek coating?

Tumble lube or normal grooves?

Plain base or gas check?

[Ausglock]

They all coat fine. Pick the one that suits your application.

9 days and still no delivery. star track express are a bunch of loosers who have lied consitantly and still not delivered the product.
Joe if you read this you are being taken for a ride by them.
This is just a joke, and I am so angry I shall end this post now, while I have some civility left.

I had same problem, it seems the product goes to Sydney first as Star don't have a base here in our area, and in my case it was delivered by private contractor. be patient it will get to you I'm sure.

I am only 4 hours away from HI-TEK. Startrack express send it to sydney and then Canberra and 4 days later it arrives here in the Grafton depot. I could walk to Hi-teks place in less than 4 days.
Startrack suck.

[SpotHound]

Star Track blows, my last shipment spent 5 days in the depot, 2 days touring the suburbs, then apparently they tried to deliver
but I was not home, funny that I was that day and had the screen door open and dog ready to bark.

Lie lier pants on fire = Star Track.

till they are dry to the touch. 3 to 5 minutes.

When I coat, I only tumble 10-15 seconds and place the bullets on a screen to dry with a hot air blower for 10 minutes. Then it's off to conveyor oven (large pizza ovens) 10 minutes at 400.

Just remember, very light staining on first coat.

[Danderdude]

I've gotta ask again, what happens when you heat this coating to the 450F / 230C range?
At what temperature does an alloy lose its tempering and become annealed?

Anybody with an oven, hardness tester and 30 minutes want to contribute to science today?

yep they sure take the work out of it, but then only using them a couple times a year I've got them in the way the rest of the time

OK, 15 gr 2400, 3x green in 30/30 @50, 1600fps is a NO GO. 13 gr gave bad vertical stringing. 20 gr. LeverE was good for accuracy but 1300 fps. Back to PC for rifle.

This is what I got off the choreboy/brush - doesn't include the junk on the patches. Big time sewer pipe. Bbl was cleaned before this outing. 60 rnds but was bad from the get go.

Popper..
I have never ever seen anything like that before from coated bullets....ever.

I have used them in rifles of: 30/30, 303, 357Mag, 44mag, 45/70, 32/20, 310 and they have all worked 100% fine with 92,6,2 alloy.
What you have there defies belief.
I am speechless...

Why take it to 230deg C when 200 does the job?
Seems like a waste of energy.

[Danderdude]

Because I believe that 200C anneals away all of the tempering that water dropping adds.



To get that back, especially for rifle boolits, you need to ramp that temperature back up to 430-450F (220-230C) and then quench. If Hi-Tek can't stand those temps, it's worthless for rifle rounds. I personally cannot justify the expense of HT, an oven, hardware cloth, etc if this is a one-trick pony.
