There are a bunch of threads here and over on Accurate Shooters forum worth reading.
Views on this have changed over time. The current view is either don't anneal or anneal after each shot. The benefit of annealing is it provides a more uniform neck tension and it may also improve case life.
As far as the case life there is a argument that the majority of annealers in the market do not properly heat the case to sufficient temperature to re-aligning the molecular structure of the brass. If you were to achieve this temp with these units then you would also ruin the entire case because the time/amount of heat applied would be annealing/softeneing the entire case and not just simply the case neck. The only type of annealer that can quickly achieve these temps while keeping the heated area isolated is an induction coil annealer. There is one unit on the market that has extensive testing to prove its claim, the AMP ($1500).
