the method I described on how I do annealing with my brass's neck EVERY reload....
much of all my brass are broken into lots of 10 for range and field work... varmints, target shooting, load testing etc.
I have lots of brass of 10 count, that I have reloaded up to 50 times and counting with ZERO neck splits..
SO... it seems to work....
I appreciate MR. Camuglia taking the time to post his explanation, and I respect the information put forth...
however the way I've been doing it is rather simpler, and the results I am getting evidently seem to get the job done.
One group of 10 pieces in a lot group, in 223... have been reloaded 110 times now in testing it...Range pick up brass, Remington Head Stamp...
out of a group of 10, in that many reloadings, there has been 3 casualties in that lot #.... each were operator error at the reload bench, with the press or die...
nothing to do with the annealing method...
bottom line, there is more than one way to skin a cat....
I have played with annealing brass, and drop into a small galvinized bucket and put it in the freezer to cool off for 30 minutes, while doing something else...
that had the same results as just letting it air cool...
