got a bunch of 30-30 brass that's been fired multiple times,so thinking of a neck-annealing session.
I"m thinking I should anneal before fl sizing.

what heat color am I watching for.I'm told it only takes a couple of seconds to do the job.

thanks !

There is an excellent article in the technical section on 6MMBR.com on annealing.

In it's simplest form, you can do it with a propane torch and a pan with enough water in it to come half-way up the case when they are stood up in it.

Heat the necks a dull red in dim light, and tip them over in the water.

But:
If you are shooting 30-30 in a lever-action, I'd say it's unusual for the cases to last long enough to require annealing anyway.
Usually, they stretch so much in a lever-gun that they develop an inside stretch ring about a 1/2" above the head that you can feel with a bent paper-clip.

If you can feel a stretch ring, toss them.

it the article, if the case ever "glows" you've gone too far.

I built the machine below to keep the process consistant. More details are here http://s121.photobucket.com/albums/o213/jmorrismetal/annealer/

I also have five of the "blades" left if any one would like to build one.
