Fill your pan with approx 1 inch of water. Stand your cases on their heads in neat rows. In a slightly darkened room direct the flame of your propane torch at the neck of the case. Do NOT heat the neck until it is cherry red. Heat it until you just see the neck starting to turn red ,remove the flame and tip the case into the water. Your case is now annealed. Dry your cases ,lube and resize as you normally would. Make sure the inside of the cases and primer pockets are dry before priming. There will be some discolouration on the neck area so you may want to run your cases through your polisher. If you heat the necks too hot they will be too soft to properly hold the bullets firmly. Simply load these cases and fire them single shot at targets. After you fire them and resize them again they will start to work harden and will be fine again. Hope that helps.
Also use the pan method long ago and later switched to the rotating holder in a drill. I think Hornady also makes this kind of kit. Not too expensive. You can make it yourself by taking a socket with a bolt through. You can also use Tempil to show you the right temperature. Do not apply it to all cases since you struggle afterwards to remove it. Just use one as an indicator and count it down. Then use it as a benchmark for the rest of the cases.
Also read later on reloading forums that one should not anneal too much since the case would loose too much springback on the neck area. The recommendation is that you should hold the case in your hand while holding the neck at the propane torch. The momemt it starts to burn your fingers drop it in the bucket. I found this method to be a torture. Best way is to count it down until with the first one and thereafter use the counts as the benchmark for the rest.
Lastly if the carbon buildup is only on the neck area it is fine, but the moment it spread to the shoulders there is usually not sufficient pressure or the shoulders was sized back too far during sizing.
