I full length size everything, and if I can buy a small base sizing die, then it is full length sized in a small base sizing die.
I have mulitple target rifles in 30-06, 308 and .223. My ammunition has to fit all of the rifles of the same caliber. I cannot affort the luxury of neck sizing or partial neck sizing. As some of the time I shoot the stuff in gas guns, the brass has to be smaller than the chamber or I risk function issues.
I took one set of 100 LC66 cases 22 reloads in a M1a without a case head separation. I full length resized them all. Incidentally I lubricated the cases and that was the main reason they lasted so long, but regardless, I still took a set full length resized set of brass 22 reloads. Not all cases lasted that many XTC matches, at least 20 were lost in the weeds, but I am certain of the surviving cases, they went 22 reloads.
I don't recommend taking rifle brass that long because I found brass erosion in the bottom third of the case.
My brass life was limited by case neck cracks, body splits, enlarged pockets. Never had a case head separation, cases with brass flaws were sectioned, never the hint of a case head separation.
If you set up your sizing die with a cartridge headspace gage, bump the shoulder back .003" from a fired case, your brass will last a long time.
