I understand the reason why some anneal but what I am not clear about is what causes necks to become weak to the point they split, or neck tension issues?
Based on what I reload, and how I've been doing it for many moons, I've never experienced any problems that annealing would address. Examples with .270 win., 30-06, 7mm RM cases. My common load is with large or maximum charges of slow burning powders. These high pressure loads never created case failure any where near the neck. 99.99% of case failures have been just above the case head, where it will begin to separate, but not until after at least 12-15 reloadings for belted magnums, and even more with the non belted cases. I neck, bump shoulder's when necessary, and keep all brass at precisely the same length. Nothing special or different than what most do.
So are .223 cases more prone to neck failure than larger bottle neck cartridges, thus the primary need for annealing? I had one case for .270 win. that separated in the middle of the shoulder a long time ago, but I found the cause was from accidentally groving it when I was using the Wilson ream and chamfer tool. That is the only time I can ever remember a case that didn't expire just above the head, and it was my error during case preparation that caused it.
I tried annealing back in the early days, but since it didn't change anything, I discontinued it.
