I used to turn the necks of my 220 Swift and 22 250 brass but found with both calibers that the brass actually thins after firing a couple of times. I had more problems with brass lengthening than getting thicker. Now understand that this was due to shooting hot loads through both these rifles. I usually just neck sized the cases then run them through my case trimmer. Still a PITB. If you can, I would just reload or reform brass that didn't require turning.
