simple Hi-Tek coating

[Stephen Cohen]

Nothing wrong with Norinco in my view, had one before our Socialist loving government decided we could not have them any longer. Nice shooting . Regards Stephen

Have the lead into the rifling checked (also called throat)
My 45 leaded like that until I had it throated. sharp start to the rifling caused it.
no leading after getting it throated.

The up side to it all is that the vast majority who have failures, do in fact take note of advice and have no further problems. Given all the different alloys and mystery metals used by many of us it is only natural a problems will come up pretty often with those new to this coating, the vast majority of us, myself included are tight ---- and are willing to go the extra mile to get a questionable alloy to work, for instance acid wash. I am sure when Joe created this coating he did not envisage the amount of different and often unsuitable alloys that we would use, the fact that most can and do get used with a large degree of success says much for this product. Contamination in any form is not your friend. Regards Stephen

I have Niobium contaminant, it has come from monotype letters that I pre-mixed with tons of WW 20 years ago . At that time I thought we will have an unlimited supply of WW and Mono and Lino...

30% HCL (I use concrete wash) sizzles and makes my silver shiny alloy gray,dark,dull and very good to coat. Otherwise it won't coat even remotely properly. (Is that english?)

Last week's colours,I made 70 lbs of 44's:

Petander, you need some red, white and purple and you'll have a nice Christmas mix for decorating the tree.

[Stephen Cohen]

Petander you have come fare and cast some of the prettiest cast, you also need some candy Apple red. Regards Stephen

The left one was smashed with a 4# hammer on anvil.

Here is Modified TMG Gold.

I baked 335, 465 and 615 grainers,all mixed in one batch with good results. 11 min @ 190°C.

The .22lr looks a little under coated there

Results looks great.

Thank,yes they are good even with such a weight difference in one batch. TMG is very good and forgiving.

Another main factor is my very rare wind tunnel designed custom tray.

Not to mention it's very avant-guarde in appearance - functional and yet it has that air of carefully designed indifference.

Is letting the bullets stay too long in the oven detrimental? I mean if you get them to temp and they stay another 2 minutes, other than the color getting darker, will it cause coating failure?

Will not hurt them at all.

Look at post #13797

Hot dang!

Funny things happen when I trust my memory.

That looks like Tru Blue, right?

That is Zombie Green in bad light.

I managed to underbake ZG again... it really is my mystery colour. I get dark overbaked-looking bullets that fail wipe test. They smash good but bake in the barrel.

I should dump all the meters now, stick to the working "dial-200-bake-10 min" -system... I was using four thermoneters last week, trying to optimize colours. Inside bullet,outside bullet, oven in temp mechanical,oven in temp digital,bullet outside IR temp...

Maybe even write down the settings, I went by my memory after half a year baking break. Well it's only 70 lbs of triple coated 44's to melt...

[Petander]

As usual TMG Gold is perfect. Very soft 8-9 BHN lead here.

I can hit that 75 meter bullet trap all day with this mild plinker. Shiny clean barrel.

Petander,
It may be not all lost. Have you tried simply re-baking some?
Re-baking will only darken colour a bit more, but this extra time in oven should finish curing.
Have a go and post results

Will do,thanks - I have heat treated some when this happened before. It must be my (Niobium) contaminated alloy reacting differently with ZG,playing tricks. Black is kinda strange too,paint-like,not glossy glass at all.

Look at this beautiful TMG Gold, with the same bake it can take anything including magnum pressures / speed with very soft alloys.
