Pics of my first annealling attmept

I practiced on several cases before moving to these. I exposed the cases to heat for 10 seconds approximately 3 inches form the base of the torch. I noticed a few of the brass have the heat mark a little further down the shoulder than the rest. I was in a relatively dark room and noticed when I took the heat away from the brass most of them had the same dull red color to the neck.

I would like to go test these with my full power load to see if I have helped or hurt things.

Any observations or comments ?

I think you overheated them. 5-6 seconds is more what I use, based on the use of some temperature sensitive crayon. The brass shouldn't glow red in the dark from what I have read, been told, and understand. Even dull red is too hot.

I'd cut the length of torch time down to 5-6 seconds.

the look is pretty good.

Since the exposure to heat time is tied to the amount of the heat (hotter needs less time) , so I cant tell if you over-cooked them or not (if they glowed cherry red then you over-cooked them no doubt). An easy way to tell is to feel them with a clean finger and ask if they have a squeeky clean feel? IF the answer is yes, then you got it right.

did you use a propane torch or a MAP torch?

don't try to anneal your cases so they look like new Lapua brass.

none of mine look like that. I practiced on quite a few with and without the temp paste. the longest I've ever had to anneal any case was about 8 seconds.

did you tip them over in water? dunk them in water?

if the case heads got too warm that can be dangerous.

in a propane flame, you should anneal up to 7-8 seconds or just to the point when the flame creates the dull orange burn on the shoulder.

I am going to test them on Saturday. Just to be safe I will load a few light and see how they look compared to an unannealed case.

They do have that sticky clean feel.

I used a propane torch. I did not dunk them.

just aim the flame at the neck only. some of the flame will hit the shoulder by deflection anyway, but do not aim for the shoulder/neck junction and definitely do not aim at the shoulder.

When I anneal, the flame is at an upright angle, maybe 30 degrees, and I put the cases into the tip of the flame straight up. That way the deflection of the flame is going up towards the case mouth. I ONLY flame the necks.

Google "brass-o-matic" and watch their automatic annealer with 2 torches.
