The metallic colors will stand up to a higher pressure. So, if your going to shoot medium to full bore jacketed loads in your rifle, I would suggest you coat them with the Gun Metal. I'm not sure about the Zombie Green. I haven't used it yet. But have shot the Gun Metal with three coats in my .308 at jacketed speeds with no leading.

You and Gremlin have high hopes. I drank all liquids I have available. I need it to soothe my nerves for this holiday break. (that is after I send out dozens of orders I have, and before Christmas, if I am not too under the weather LOL LOL)

Merry Christmas All.
I'm a commerial ammunition manufacturer and I have the following comments to add:
We test a LOT of new products, with a stern eye on repeat consistancy and succesful product outcome. We imported some Hi Tek to try about 8 months ago and put it in our R&D cycle (which means I as the owner got to fiddle and test it)
IF you follow some simple rules, this stuff works, EVERY time, but dont deviate from the rules.
(We have only tested 9mmP and 357SIG properly, but the 357 SIG is a overpressure load and should replicate any hot handgun load out there- We did some specialised brass mono bullets in rifle calibers with very good results too, but thats another story)
First, Lead- know what you are working with, scrap lead wont always work, if its too soft it will lead- no matter what you do to it. Foundry lead FTW!
Clean your cast lead- this is important- and is underemphasised in this thread.Any contaminants on the raw bullets will wreak your efforts. We currently use a dishwasher for best effect but are moving to a solution of Caustic at 80 deg C for 20 minutes and then a HCL bath for 5 minutes. That may be overkill, but we cant afford failures.
As Trevor has said, get your mix of solvent and powder right, and make sure it gets time to react- at least an hour, with regular agitation.
Allow enough time for the stuff to dry, 10 minutes wont always work unless you are in the desert.
Dont overagitate or underagitate the coating process. Swirl hard until you hear the acetone/ MEK has almost evaporated and then dump out.
Use decent racks for drying/ baking. Air flow is important.
Get a decent oven with stupid strong airflow. and measurable temperature. Without this you are wasting your time. Follow the instructions.
(YMMV) We coat 3 times, with a 2 hour drying period between coat and bake. It works in our climate every time, YMMV. We resize after the 3rd coat and water drop between the last coat and the restrike.
I have shot 8000 9mmP full strength 124gr Hi Tek bullets out a Beretta 92 (new) without cleaning and found no visible trace of leading when I finally cleaned the weapon (and I looked hard).
Finally, it takes some trial and error- we put that down to diffent environments affecting this amazing product in different ways, but it works. the proof is that our two sponsered National shooters that are going to the IPSC World Shoot in France next year are both taking our Hi Tek product with them, and I wont ever shoot another electroplated bullet by choice again. My next 80 lbs of powder are due here on Wednesday having cleared Customs. Thanks Joe, and, by default, Trevor- great product!

Sorry to be so long in getting back to you. Yes you need a convection oven not a toaster oven if you want some color consistency throughout the tray you are cooking. I tried my oven without the convection and still got bullets I could shoot but they were four or five shades of the color I was using. I would think that you might want to cook a little longer without convection to make sure all of the coating was cooked well enough. Might have some cool spots that didn't get the coating up to cure temperature.

Congratulations, world wide acclaim.

Nope I even gave him an extra two days after Xmas, I think he has consumed them all by himself...

Thanks much Avenger. As my better half said, "we are an overnight success", taken over 24- 25 years.
This product range has been an on going development project, being improved as we go, with very dedicated shooters that fed back their results.
Now, we have tweaked final recipes close to ideal conditions, that meet 99.99 percent of end use applications.
With demand for newer colours, we have run into some hiccups, where we had not so good results with compatibility issues with newer trial mixes. But that is development, You win some and loose some. Because of unique nature of these coatings, you cannot rely on any help from outside sources, as no one has any expertise with such technical details, and there is no other product manufacturer that has equivalent products.
Thanks for your support and feed back.

What do you mean by"restrike"? is that sizing?

Yup...

I had a good go, (could not finish it all) but I did get some help with friends and family, (17 of them) celebrating Christmas day with us.

[Gremlin460]

Its 113F 40% humidity today, If I wanted to coat today I would have to nearly double the acetone component to get any chance of swirling. Damn its warm!

[Ausglock]

108Deg F here and 40% RH.
Indoors in the AC.

Been a warm fall and winter here. Our heating bill is way down from the usual. We made up for it this past summer. Cooling bills were up. Even had to replace a unit that failed this summer. It wasn't that it was extremely hot just so many days above 95. With the exception of the replaced unit the bill probably will even out over the year.

I haven't had much time for casting and coating. We usually celebrate Christmas from about December 20 - January 1. Since the family is scattered we have several get togethers.

Can't even load for my .308. I cracked the expander while trying to remove a stuck shell. One on the way from Hornady.

Did get in a trip to the range with the grand daughters, one good thing about them being out of school. They love to shoot those Hi Tek bullets. Shot all of my .308 over half of the .38 I had loaded and about 150 rounds of .22 LR. They would have shot up all of my .44 mag. if I had not left it at home. Never seen girls that like to shoot as much as these do. One of them looks like she will be a much better shooter than her Grandad with the pistols.

Got an new Hornady powder measure and some Lee molds from the wife for Christmas. So maybe I can get back to it next year.

Hope you all had a Happy Jesus' Birthday and wishing you a very good New Year

Had a play with the wall oven this arvo.

Managed to fry a 40 amp SSR. Hooked 2 elements to it... Didn't like it and blew the breaker.
I now have the PID running to a 12v/240v 40 Amp SSR that in turn runs to a 240v/240v 20 Amp SSR.
Running 2 elements from this works, but the 20 Amp SSR is getting very warm.
Going to run a seperate SSR for each element.
With only a top element and the fan element running, The oven reached 200 Deg C in just 2.5 minutes!!!!

Here are a couple of pics. The wireing is a mess and will be cleaned up. Need to get a few more SSR's.

This oven shows real promise. The fans pushes a huge amount of air around the oven compartment.
The fan switch on the door that stops the fan when the door opens saves a lot of heat loss.
Closing the door had the temp drop from 200 to 195. Recovery to 200 was 30 seconds.

I like it.....

Ausglock how is this oven working for you with both elements running?
My thermostat is going bad in my oven so I am going to have to something like this.

[popper]

Ausglock - you MUST put a big heat sink on the SSRs, specially if run from 220. Get a computer PS box with fan (220) and mount inside. Hot SSRs have a thermal runaway problem.

[Ausglock]

This oven is working bloody great.
Still only running 2 of the 4 elements.
The SSR's are mounted to their alloy heatsinks and screwed to the sides of the oven exterior walls.
By having 1 ssr to each element, causes very little heat buildup in the SSRs.
The digital countdown timer is a great bit of kit too. When time is reached, it flashes and sounds an alarm on the red round thing next to it.
Red reset button above gets pressed to start the countdown when trays are inserted to the oven.
Oven warmup time is 2:30min.
2 trays (5Kg) bake time is 7:30 mins.
I have been using this for awhile now and the repeatability and consistant baking/colour is great.
I have another wall oven here to modify as well. Just need time to do it.
Photo of the first oven showing the final layout of the controls.
2 toggle switches.
One is master control. other is heating isolator. This one is not really needed, so I might remove it at some stage.
