It turns out that the bras I annealed was soft a little to far down and actually buckled and shortened when I seated a bullet. I pulled the bullet out of them and threw the brass out. I'll have to be more careful heating the case necks if I make any more brass. I need to heat them for a shorter time so the heat affected zone is smaller.I had that happen to a couple .223 rounds. Seating/ crimping die was set up too tight. My fix was to use a separate Lee factory crimp die and loosen up the seating die so that wouldn't happen again.
Reloading definitely has a lot of opportunities to learn.
Annealing brass is a true art and something I don't even try. But they do make heat 'paint' to let you know when it's hot enough. Cherry red would be way too hot. Unlike steel, brass doesn't have a noticeable red color change at the temps you're looking for when annealing.
If it were me I'd be using one of the machines verses any hand type method for uniformity.
