Annealing Questions

[Mike in Oregon]

Having never annealed, I have a few questions. I have the Bench Source annealer, and bought an additional torch mount.

I'll be reloading for the 17FB thru 6.5CM. Would dbl torches even be necessary, especially on the itty-bitty ones?

Get 450 & 750 degree tempilac. Paint 450 on the outside of case, shoulder to base, and 750 inside the neck. Start with 1 torch and 6-8 seconds. You want the 750 burned out of the neck and no more than 1/2 the 450 melted on the outside. The key is to get the neck shoulder up to 750+ but never get the base over 450.

It's impossible to anneal at 750F. You need to be at 1050-1100F for 1-2 seconds. Real annealing data has been put on this website many times. Do a search.

It's impossible to over anneal the body. 750F for several minutes does not anneal. I anneal until the neck just turns red with a single torch. About 8-9 seconds in the flame. I hold the case in my neck turner case holder and rotate with a drill. I push the case into the flame so it wraps around the neck. Most setups in videos show the very hot pointed flame tip just off the case neck. Some of the videos show the side away from the flame being colder. I see the entire neck red at the same time this way.

Holy crap. Like I said, this is new to me but I have never heard what you just said. I learn something everyday!

I use a single torch and have no issues. A single torch is much easier to manipulate/manage than two. As for as annealing goes, watch and read as much info that you can absorb…..because it is still a guess if you are actually annealing with the common methods the average shooter employs.

2 torches get the neck shoulder junction hot without heating the whole case.
(Less time in the flame)
I've never used tempilac. I Just get them to the edge of glow.
Use a couple of dummy cases
Standing there, fingers on dial.
Make it glow turn the speed up until it is right at that edge.
There is a learning curve to flame strength and time. Nothing is perfect.
Have fun playing with your new toy !

The 750 tempilac is just a go by to make sure you’re getting well over that. Case necks do turn slightly cherry red, when viewed with the lights off. The 450 is to makes sure your not getting the case head too hot. You can dam sure over heat the case head.
Not sure I’d claim to be an expert running a drill and torch.

Pick and choose your “expert” carefully. Online opinions are not always reliable. Get on the annealer manufacturerers websites and research it. I chose the Giraud annealer 10+ years ago. I was taught to anneal in 1986. The technique then was to set cases in a cake pan of water, about half way up the case. Heat neck shoulders to just slightly cherry red then tip over in water to cool. The important part was not the get the case head too hot.
