I don’t have $1400 to drop on an AMP machine so I have an annealeez machine. It’s a one torch set up. Based on almost every video I’ve seen with this machine the case should be in the flame for roughly 5 seconds. I have always done this but I just noticed something. With my Alpha brass I have what looks almost like a “burnt spot” on the neck. It does not do this with my Hornady brass or Federal brass. I did this in the dark and the cases just barely had a glow of red when they came out of the flame. Some people say no glow and some people say you want the glow. The brass was tumbled in rice for 3 hours before annealing. The last time I annealed these cases I did not see the dark blackish spot. Is there any way yall could look at these pictures and tell me if I just screwed up my cases? Please don’t annihilate me for my ignorance and lack of knowledge.
Yep I use redding imperial dry Neck lube on the inside. Just a light coat. And Yeah my rifle seems to like it I don’t really see anything wrong with it it just really ensures that the bullet ain’t going anywhere. Bullet goes in smooth and easy, doesn’t strip off the jacket so I don’t see a problem.
I would say the dark spots are probably because your Tumblr didn’t clean 100% on the outside of the case or maybe left a dry dusty residue on it you cannot see with the eye because it is a dry tumble and that happens. I wet tumble with stainless steel media And it gets it squeaky clean. But if you look down past your shoulder you can see how far that rainbow mark is down the case and it looks pretty good to me .that’s mainly what you want to base your annealing marks on visually because if it goes too much more further down than that then too much of the case has been heated. But yes long as it doesn’t glow red you should be good and you shouldn’t worry about the burn marks because my guess is your method of cleaning left a dusty residue on the case , but if it does glow red then thats when you start to burn Zinc out of the brass and ruin its properties. But you also don’t want it to be under a low flame too long to reach that because you also don’t want the case to get too hot too far down the case and make the body to soft. So if you see a red glow thats a No No. You kind of want to find your happy medium with how big the flame is and how long it’s under the flame. Tempilaq does help. Like you want 750f to he reached on the neck and 450f reached 1/4th down the body. But once u start heating the neck past 750 u run that risk of over annealing. And same with the body if u get 450f half way down the case they the body of the case to be to soft aswell. And if you want to test my theory, after you dry tumble your brass clean off one or two pieces with soap and water and rinse it very well and let dry and see if that changes it to see if there is no burn marks like the ones you are seeing
By the way, all questions are welcome. If anyone tries and belittle you as such, you let me know. We all have to learn somehow and start somewhere.
Hey! No worries about dropping that money. Not necessary at all. As long as you are getting the results you want, that’s what matters. However, i would checkout amp’s website for great instructions and info on annealing itself for brass. Color is not a great indication of annealing. Here’s an article that will help clarify some of the studies done on annealing itself, in regards to color (the look of annealing) and what you should expect as a benchmark: https://www.ampannealing.com/articles/52/salt-bath-annealing--does-it-work-/ Hope this helps
