[QUOTE="Hugnot, post: 2030762, member: 115658"] I spent less than $25 on my simple propane tip annealing after 3-4 cycles. I always outside turn necks and periodically, like every 6-8 cycles, turn them again using the same one of two (.22 & 6mm) RCBS neck turning tools because it is next to impossible to reset them exactly. I see very few signs of forward brass flow (just turning off crud) and at that time I am ready to toss the brass with the exception of .223 loads where I like to get over 15 cycles. The outside neck turning helps to get uniform neck wall thickness and prevents excessive work hardening caused by squashing necks, reducing radii then increasing radii with the expander ball. Frequently, I skip using the expander ball entirely. Achieving a suitable plastic state of neck/shoulder brass by annealing helps to provide consistent neck tension and extends brass life. I try to get Lake City brass for my .223 loads. I have found LC brass to be extremely hard headed but well annealed at shoulder & neck, and take care to preserve this by standing that (and other brass) in water before toasting necks with a propane flame. If you shoot them more than 4X, annealing will help. I avoid rocket ship loads and depending on round keep pressures within SAMMI limits with the exception of .243 Win loads. I used to write computer programs for smart science guys so I can handle stuff like this - just another process. [/QUOTE]
