Re: Case neck turning.
Back when we still had groundhogs I used to turn the necks for my varmint rifles. 220 Swift, 22-250 and 22 CHeetah. It was required for the CHeetah as part of the case forming process. If you want to put a number on the benefit of neck turning, I always felt like neck turning maybe shrank groups .1 to .125 at 100 yards. If you are loading for a varmint rifle, or certainly for a true target rifle, it's worth it. For others however the benefit is very little for the trouble. I think I tried turning necks some for my 25-06 years ago but decided it was too much trouble for a deer rifle with my favorite Nosler Partition load that grouped only 1 1/4 moa anyhow.
I use the Forster turner also by the way. Not sure if it's the same one though as mine is the mini-lathe hand-crank style. When I think of a hand held neck turning tool I think of the kind where you truly hold the entire tool up in your hands.
