Annealing test

FWIW, here's a test I did awhile back with salt bath annealing. My results were similar to yours, though not as bimodal.

Salt Bath Annealing setup and quantitative assessment.

Just finished constructing and first testing of a salt bath annealing system. First post will just be the components and schematics for the rig I built. Second post on opinions of use and efficacy testing. Links are amazon, cause they’re easy to do. Shop for yourself. Prices are estimates for...

That's awesome.

Well done.

I would like to see an analysis of what happens to the case and the bullet during the initial stages of firing. It seems likely that the neck first expands to fill the chamber (thus releasing the bullet) before the bullet even begins to move. In other words, it Seems like neck tension should have no effect on burn characteristics. brass hardness in this model could have some effect I suppose. Interesting subject.

Ignition starts at the primer, so I suspect everything starts surging forward, and therefore, the neck would be the last part of the brass to expand...

Guys that master the neck, can use crap brass and still get accuracy

That depends on were the " crap" in the brass is. Necks maybe depending on how bad they really are.
Big Internal volume differences and really poor flash holes different story.

AGREED.....

IMO if you are going to question and argue - show YOUR data. I, like OP, will stick with my low speed set up of a socket and torch.

The socket and torch works just fine, Don't let anyone tell you different
