I've never shot enough to worry about Annealing. If I get 3-4 out of Magnums and 4-5 out of standards, I'm cool. I'm more OCD when it comes to my Reloading, I tend to work up a load, then try it in new brass. I 'always" set up my FL Die to partial size/setting headspace on the shoulder, just enough to easily chamber. If the combo of rifle/load like it in New Brass, I will set up 50 new brass rounds & set aside "just for hunting". I then will shoot remaining brass until it gets loose primer pockets. Throw away. Most of the time, however, rifles tend to like the load combo in a fired case. If so, I use 1X brass "for my hunting loads". I then go to battle with my feverish, OVD Mind mildly confident that I am "set", lol.
The purpose for annealing isn't for making the brass last longer, that's a side benefit.
