Re: Annealing Cases

Chain- this may not be the best way to do it, (it's how I do it so I know it's not the best), but this method won't require you to see color. I heat them for about 4 seconds. That timing corresponds to what I call the brass catching on fire. You can see it in BBs video and you'll see it when you do it. When it reaches the "stop" temperature a flame starts to form trailing the brass on the opposite side of the torch. The first time I annealed I used a templistick. The templistick melted when I reached this same condition. So I quit using it cause it's combersome. The 4-5 seconds and the flame corrsponded with the templistick melting. Hope that helps.

Drying the cases

I generally use low temperature in an oven.

You can also try really hot water for a final rinse and air drying.

If it's just a few I put them flash hole down on the air outlet of my dehumidifier in the safe for a while (being sure to not cover too many of the holes).

Some guys use compressed air (if they have it in a workshop).

Hairdryer will work in a pinch.

I always leave them overnight after any of these to make sure they are properly dry prior to loading them.

Re: Annealing Cases

The safest way is just to set them upside down to dry out for a few days. Here in sacramento, the garage gets nice and warm!

Re: Annealing Cases

Thanks JMASON that's what I will do. Would a bath in isopropyl alcohol help in the drying out? After they are cool of course.

I can't help you here. I just shake them out and put in a tray primer pocket up to air dry.

thanks for the videos. Before annealing and turning the necks I had 1.5moa at 400yds. Today I shot again after annealing and turning the necks it shot almost 1moa tighter with the same powder charge. Having less than premium brass available for my 7wsm it sure did help.

I am also color blind. You may not see the same color but you will see the contrast change as it heats up. I am sure I did not anneal exactly uniformly it was my first time doing it. I shot three different charges annealed and turned and without all brass was shot 5 previous times. The annealed and turned shot from .5moa to 1moa better than the other. It is worth trying
