How do these look? After the last firing two necks had small cracks so I figured I’ve give it a shot with the torch.

Looks overdone to me. I'd do it for significantly less time.
You can overdo it. |

I’ve noticed that some of the annealed factory cases come looking very similar to this so I figured I’d try to mimic that and it the cases crush then oh well it’s only 20 cases. |

The problem you have with OVER-annealing -- you may have softened the case head, which besides holding the primer also keeps the bottom of the case from grenading into your barrel extension and blowing out your extractor.
Military cases will look like that after a fashion as the brass oxidizes. Civilian cases are often polished after anodizing, so you may never notice. |

Overly annealed brass may also impact neck tension. So there is that as well.
Get some tempilaq and try again. You'll likely notice a huge difference in the amount of heat you need for a proper anneal vs what you dumped into those cases.

Use tempilac. Hit the toobz videos. It can be hard to see, but you will get there.
Those look a bit cooked to me, but could be potato lighting effects. Dirty cases will also have more discoloration. Are you using an automatic system? Even cooked, those look pretty dang uniform.

Heres a pic with better lighting. I used a deep socket in the drill to only expose the neck/shoulder.

 I over annealed brass and then F/L sized it. UNEXPECTED RESULTS!!! https://www.youtube.com/watch?v=9HfjRKrbYbo |

Quote HistoryThis was awesome. I didn’t heat these up anywhere close to what he did. After watching that I don’t even think these are overdone. The first pic I posted may have been misleading. |

 Here is how my 300 blk looks annealed with 750 degree Tempilaq, screwdriver socket method. If you have any once fired LC brass, unpolished, that would be a good side by side comparison. |

How they look isn’t as important as whether or not you got the neck/shoulder hot enough but not too hot. That’s where Tempilaq comes in.
What method did you use? I use dryflash3’s Low Budget Annealing process. I make sure I have good light, and I look for the Tempilaq to change, then dump that case. Yes, you do start to get a feel for when the stuff changes, but it’s still important (to me) to actually see it change. |

Skip the Tempilaq.
Do it in a darkened room and watch for a slight glow from the neck that occurs at the same time that the flame changes color. Annealing achieved. |

I haven’t been annealing cases very long, but I found a method that keeps from overheating the case heads. I actually heat the case while holding it in my bare hand. “Too hot to hold” is way under too hot for the case head.

I actually heat the case while holding it in my bare hand. “Too hot to hold” is way under too hot for the case head. That's old school. I used that method with 308 cases before making an annealer box. I was worried a 223/556 would heat up too fast and I'd drop it before reaching the desired annealing temp. I never timed the bare hand method and compared with tempilaq. |
