95% of my reloading is for bolt-action rifle (currently 5 different calibers) and I neck size (with Lee Collet Neck-sizing die) because of one reason:
It is much simpler (no lube required) than FL sizing.
Is it more accurate than FL sizing? Don't know since I don't FL size a brass after initial firing for comparison. Once I do find an accurate load, accuracy is repeatable with each subsequent neck sizing load.
Does the brass last longer than FL sizing? Don't know since I haven't run a batch of only FL sizing to compare. Currently, the 30-06 and .270 neck-sizing reloads are on the 6th cycle with no sign of failure.
I like the Lee collet neck-sizing die and highly recommend them.
