What is a good neck turner? Should the necks be turned period?
As far as weighing the brass, I am assuming to sort by weight as differing weight would indicate internal differences in the brass?
Sorry for the dumb questions here. I am learning as I go.
Thanks for all the advice so far.
If they are not concentric, shoot them as practice. Then check to see what runout is on a just fired case (should be low or none). Then check runout on the necks after every brass prep and loading step to see where runout is entering the process. Once you know wher the problem is you can figure out how to fix it.
I turn necks on new brass to clean up about 60-75% and never turn them again. I use the Forster neck turner and like it a lot. After handling the Sinclair unit though I think I would buy it instead.
I hate weight sorting brass because you never know where the weight variation is coming from exactly. And I just hate weighing brass for some reason
so I would pick up some Nosler brass and skip that step, it would probably largely negate the need for neck turning for a factory chamber and barrel as well.
