I'm relatively new to annealing. So far I have adhered strictly to what the Tempilaq, the books, and the brass was telling me. However, yesterday I got lazy and ruined 50 pieces of brass.
Instead of setting everything up and getting the timing down using Tempilaq, I just eyeballed the torch distance to be around where it was last time and assumed the machine was still set where I left it.
And then, I over annealed the neck so much that my mandrel neck die smashed the shoulders....Which happens when the shoulders are too soft.
I will keep annealing because it has improved accuracy and helps maintain a consistent bullet hold . But shortcuts will bite you in the butt .I guess some dense folks need to experience what the books warn against before they listen .
