Also concentricity gauges, 1 are they also worth the cost and effort ,any practical accuracy gains ? if so which one do most folks going with these days, I see Horaday has one that can "correct" concentricity anyone have feedback ?
I just bought a Forster bump/neck bushing die, have only used the expander ball type dies thus far, Ive been reading about these ex pander mandrels , are they only used with neck turning or could one use them when neck sizing with bushing dies ?
regarding "donuts" how to avoid / correct them when using bushing dies ?
Thanks in advance Scott
Go with the no-turn necks
Keep the $$ in your pocket for now that a concentricity gauge will cost you
and use your present set of dies
