Which gas for annealing

[CatShooter]

I stand corrected. The difference is between translucent and opaque.

It is not unlike a butterfly's wing. (And I did mention oxidation layer. Partial credit? ???)

Pretty shaky ground there

How? The iridescent butterfly wing is very much like the rainbow effect in the oxidation on a case. If you looked at the case under a microscope you would see the tiny grains which refract light, like raindrops in a rainbow - or the scales covering a butterfly's wing.

You made that up!!!



The oxides on the case do not refract light. Go buy a microscope - you will not see what you claim.

In order to refract light, the crystals must be transparent - there are NO transparent crystals on brass.

They reflect light. Better?

Nope... still shaky. They are simple oxides like pigment in paint... nothing mystical about them.

Might learn something here........... ;D

Nope, wrong, It's absolutely not pigmented. But not mystical, either. It's a form of "interference diffraction".

"An oxide layer is not normally transparent, but such thin layers do allow light to pass through, reflecting off both the upper and lower surfaces of the layer. This causes a phenomenon called thin-film interference, which produces colors on the surface. As the thickness of this layer increases with temperature, it causes the colors to change."

"The thickness of the oxide layer depends on the temperature, and the thin layer creates interference effects for different wavelengths of light, and thus show colors - similar to a thin oil film on water showing 'Newton's rings'".

Nonsense - you are talking about something that is not occurring brass from annealing. You cannot just pluck anything off the internet that sounds like you want, and plug it in.

To be what you are saying, the "crystals" would have to be transparent, and the thickness would have to be on the order of 1/2 micron - PLUS, the colours would change as you rotated the case... which they do not.

You cannot save face doing this.

Go shoot yourself some more cats, you need a break.

The cases are not pigmented, that's obvious. And you admitted yourself an oxidation layer was present. The description I posted explains the phenomenon perfectly, anyone who has annealed cases has watched the color change migrate up the case body as the heat does.

You keep desperately trying to come up with something, but you are failing every time, cuzz you are trying to debate something you do not understand.

 

[Gabe22BR]

I can polish the color off , and it does effect accuracy, does that count?

Right ...

Did you use a brush or sprayer to apply that "pigment"?

Been a long winter, huh? :

Not where I live.

 

[Joe Salt]

brian then you need to get out and shoot more instead of being on here! I would be.Wish I knew how to post pic's I'd show you mine! BRASS I HAVE! Forgot have to be Specific.

[Brians356]

I was out shooting ground squirrels only last weekend, did very well. I work so weekdays I am tied to the confuser - and here I am!

 

[Road_Clam]

It's pretty clear everyone is suffering from winter shooting withdrawls, so in the mean time please just spoon some Varget into your bong , light it up and breathe deep........... we will all then feel much more relaxed ;D

Bong? What's that?

 

[akajun]

In the days it took yall to argue about oxides and templaq I annealed over 1000 .223 cases I am converting to 5.45 x39 by hand, held with my naked fingers, with a plumbers torch, dropping them into a bucket of water. Same way I was taught 20 years ago by one hell of a shooter, gunsmith, and machinist.
It ain't that complicated, a machine would be nice in that It could run on its own .

Whut?

I hope you're trolling...

 

[akajun]

Nope, I have a lifetime supply of .223 brass, and a few years ago hornady sold .221 bullets 60 gr v max blems for .05 apiece. Some guys on one of the ak boards did a special run on lee dies for 5.45 and I bought a set. I got tired of having to clean corrosive ammo out of my ak74 when I just want to shoot a few shots , and non corrosive 545 was hard to find fir a while .
It's simple, size .223 in a .222 die, trim to 545 length roughly in my drill press, then anneal and run in a 545 size die, then finish trim in my giraud.
This was probably the last time I'll have to do this as I am now out of bullets.

 

[Catfur]

And the significantly different head size concerned you not a bit?

 

[akajun]

Not really, you get a little bulge on the first firing , but you can reload them about 3-4 times safely, I tried to burst one but after 6 loadings I csllled it good enough and decided to cull at 4. Besides this is an ak 74, it's supposed to have a sloppy chamber .
I really thought by now someone would have made 545 brass by now.
