I shoot 308 calibre.
I use Lapua Palma (small rifle primer) cases.
I full length resize after each use as the cases can be used in 1 of 3 similar but not identical actions.
I don't push my loads for speed, need to be fast enough but accuracy is the goal.
My most used cases have been fired 13 times without annealing (or trimming).
The 13th fired cases will get a trim this winter, along with some of their friends who have been fired 11+ times.
Lapua don't recommend annealing their cases.
Could there be another reason for splitting necks, not just lack of annealing?
