In the case of annealing rifle brass, the mass in the case head is very large in comparison to the mass in the case neck. This mass helps to distribute the heat and keep the temperatures down. Our torch selection and setup is precise and efficient when heating the neck. This combination prevents the case head from being reaching annealing temperatures.

For the F-Class National Championships, I annealed (softened) my 284-Win necks using Brass-O-Matic for 7 seconds (longer than most) because I wanted to ensure that I achieved a nice softening of the neck for a very consistent pressure seal. It worked well (6th overall, F-Open with minimal vertical stringing) and there were no pressure signs on any portion of the brass besides a nice, desired carbon ring around the neck where it quickly sealed in the chamber.

I.e., if you don’t immerse the head in water while the shoulder/neck are being heated, you’ll anneal the entire case. Is that not true?
