TMG Gold
I have coated a few 1000 125gn Conicals to run through my Trubor at major power factor to see how it holds up with a 4 port Comp.
Also coated 1000 135gn RN for the STI Tac 5 for Std Div Minor.

Just the lighting. The liquid is very shiny gold...

Yes thats's correct: especially my contaminated alloy loves a diluted first coat after a HCL wash. I have two bottles of everything now, the diluted is for the first coat. It has 30 ml added denatured alcohol to the standard 100ml/20 grams -mix.
Just made some green 45-70 ones that way, fantastic bonding.

I don't normally use gas checks,these are old sized,lubed and gc:d bullets that I cleaned for Hi-Tek.

Can I invite all persons to please post pictures of any captured Hi-Tek coated projectiles, to see what the fired cast looks like.
I am interested in all calibres fired from as many guns as possible.
Thanks all in advance
Using the tumble coater I posted earlier, the rack and fan does a great job of both drying and cooling boolits
I like to do 5 or 6 trays at a time, works out great for cycling through the coating/drying/preheating on top of the oven before baking, baking and cooling cycle.
Never failed a smash/rub test doing it this way

An old cartridge from 1873.
The same powder charge, the same bullet, but one is lubed the the traditional way and the other with this modern Hi-Teknology.
Which bullet will reign supreme
Loads being tested
44-40
New Starline Brass.
220gn Accurate Molds 43-220C sized at .432 (bore is .431)
Load 1. 8gn of Unique
Load 2. 16gn 2400
Traditional lube is LBT Blue Soft
Hi-Tek is Old Gold
Rifles are Miroku/Winchester Model 92's.
CamoWhamo,
The coating looks great, but a little over cooked. No problem at all, as long as it passes all tests OK.
When loading and crimping, be careful that inside edge of case is not pressed too much onto alloy, as it can cause shaving of alloy.
I don't know if you bevelled internal edge of case or not.
Guys on this forum can advise you further.
Thanks for the heads up.
Is it better to reduce the time or the temp?
These were with the oven set at 200c for 10 minutes.
My oven has pre-sets rather than fine adjustments.
There is a setting for 192c (375f) Should i try that?
I have tested the oven with my casting thermometer and an oven thermometer inside and they both confirmed the oven's temp matched what was set.
Will do some berm diggin'.
My 9mm barrel is ridiculously clean with Hi-Tek & 3N37. 45-70 & ,N130 I have cleaned with five dry patches every 50 rounds or so. Only burning residue. I have verified the mind boggling , nonexisting 45-70 leading with Foul Out,The Dip and brass brush... it doesn't lead at all with the correct size.
Undersized 457 bullets gave some thin leading at the muzzle end, I found many from years back and coated them. They shot fine and the very slight leading didn't build up. Just a normal brush/oil cleaning handled it. My correct size is .4595.
In 9mm Tangwang I can shoot .357 and .358, nothing in the barrel. 358 being very accurate.
I feel like having an endless free supply of premium 45-70 bullets now. I can shoot clays @ 75 meters with a Marlin SBL all day (factory rough bore!)
Your cooking looks like mine. How much does your temp drop when you load your bullets in?
I have a powerful oven and my temp drops to only 192° C when I load,I get slightly overcooked bullets in seven minutes. It's back to 200°C in two minutes. I've been thinking about letting the temp drop a little more in the beginning,instead of a shorter time.
My bullets are 55°C when I put them in,being dried and pre-warmed on top of another oven.
I just got my order in the mail and i am going to try and make some old gold projectiles this weekend,
Cam.
Don't change anything.
If it is working, leave it alone.
But..... you can try 195 for 12
Hooroo.

Cam if you chrono'd the 2 boolits you probably found the HiTek was faster. the Hitek has much less smoke, leaves you with a clean barrel and didn't gunk up you dies/fingers
195°C / 12 min worked good for me, I'm trying to get back from overbaking to get the colors the way they are supposed to be. Got a nice Black Cherry batch with a hint of gold right now. Tests ok. Thanks!

In 200°C /12 min these would be all black in my oven. Even 7min/200°C makes them a little dark, very good shooters though. I've experimented up to 215°C ,coating works and no fear of underbaking... but no nice colours either at those temps.
Every oven is an individual,of course. My temp @195°C is the same from the beginning to the end, no initial temp drop at all. Because the oven is 215 °C before I open the door and 2kW power helps,too.
EDIT: I tried 195/12 with Kryptonite Green and it got completely toasted into bronze. I need to start making notes.
Attachment 225580
EDIT2: While at it, I gave those another green coat 195@°C/8 min. Looks more green.
Attachment 225581
Me being the Official Mystery Metal Man, my bakings may differ from yours because of my contaminated alloy. All these shoot clean and great though!

I just got home from an extended testing session at the range comparing the Lubed bullets Vs Hi-Tek coated.
2 identical Winchester (Miroku) model 92's in 44-40 with .431 bores. Both of these rifles have previously shot the same loads consistently in terms of velocities, ES, SD and accuracy.
Rifle No1 fired the Lubed bullets.
Rifle No2 was given a thorough clean and fired the Hi-Tek coated bullets.
The bullet used was the Accurate Molds 43-220C.
Load No1 was using 8.0gn of Unique.
The lubed bullets averaged 1192fps.
The coated bullets averaged 1184fps.
That's statistically insignificant loss of 8fps.
Both of Load No1 performed consistently.
Load No2 was using 16gn of Alliant 2400
The lubed bullets averaged 1282fps
The coated bullets averaged 1336fps.
That's a gain of 54fps.
The lubed load was very inconsistent with a large extreme spread. I actually shot 2 strings of this to verify because the first 10 shots were so spread out.
The coated load was much more consistent with a lower extreme spread.
Accuracy was good for both but the Hi-Tek target has a single hole half the size of the target shot with lubed bullets.
I was shooting left today, probably due the light coming from my left side.
The barrel of rifle No 2 (Hi-Tek) was basically clean after 90 shots fired throughout the day.
A single pass with a bore snake and it looks spotless.
There is some shavings accumulated at the bottom of the receiver. I suspect these might be from feeding through the loading gate or being cycled through the action. The magazine follower also has an old gold stain on it now.
Yep. My Marlin 1894 44Mag does the same thing. Loading gate takes a bit off the pills. I get green in the receiver.
Hooroo.

That is a great report. It is detailed so all can see what happens with various loads and accuracy, and comparing lube and coated alloy..
Just curious, what was distance to the target?
It is interesting that both lubed and coated pills shot left side of target. Could that be just an adjustment being required?
