Annealing

I guess it's possible to screw up annealing, but it's not rocket science.

I'm afraid cherry red could be already too hot. Like driving, it ain't rocket science. But if you don't do it right, the consequence could take rocket science to repair.

akinswi yes there is a timer you can adjust for different cases. you can adjust from 1 second to 10 seconds. My prc cases take 3 seconds and 22-250 cases took ! 1/2 seconds. You can use 1 or 2 torches.

http://www.bench-source.com/id81.html some info on it. I like the machine. There are some youtube videos with tips to cut down on the torch setup time.

Cherry red has gone way past anneal.

The good news is being in water it did not go down to the base, that is a KABOOMY!!!!

Perils of the failed 1903's that they were heat treating by eyeball. It no a work.

Ergo, I could spend a lot of time figuring out torches and the variables they have (Metal God) or I could sell a gun and buy the Annie.

Regardless, I do a 3 step process. One is a temp stick that just barely melts at 750 deg, I look for any glow (not red but any glow) in the case, I watch for the flash of discoloration and then I see if it polishes off.

Notice, I said as an experiment. The worst that could have happened was a neck split. The bottom 1/3 was protected by cold water. Guess I could have had a mid case separation. Had one of those in 300 win mag and did not know it happened until next round would not chamber.

As you went too soft, neck split is not what would occur, nothing would occur other than a loss of consistant neck tension (not sure that is the end of the world, fired off a round the other day that had a hell of a hard seat compared to the butter soft of the others and it landed right in the middle of a 5/8 group.

The case split is too much re-size and or maybe a bit of chamber oversize. The best counter is shoulder set back or .005 (I overshoot a bit). That or Lapua brass which seems to be resistant to case splits as well as neck splits

I have had case splits with Mil Surplus chambers, not sure I solved it as I shoot those a lot less and fully case supported custom barrels good chambers on my Savage actions

Its quite the fun figuring it all out.
