It's astonishing to me that so many people believe brass cannot last a very long time if you full length resize cases.
If you only f/l size to SAAMI dimensions, that's certainly the case because each time you resize, the amount of movement (working) of brass, will make it brittle and fail within a relatively short time span.
BUT, if you carefully set your F/L sizing die to your fired case headspace dimension, so as not to move the case shoulder more than a couple of thou " each resizing and anneal cases each three or four reloadings, not only will you ensure very long lasting brass tuned to your rifle, but you also benefit from consistently reliable chambering and excellent accuracy.
It's so simple to just set your dies up properly to achieve this and also, with attention to detail, obtain great concentricity of case neck/body alignment.
