Lube for neck sizing?

[1jonathan1994]

Is lube even necessary if you're just neck sizing with carbide bushings?

What about bumping the shoulder and neck sizing?

I'm debating a one pass reload on the Dillon without a tumble. Only wiping the cases off (since not FLZing), deprime/prime , bump/neck, powder, seat, shoot.
I'm hoping to not have to trim or chamfer every time with a mild load. I do have the throat length gage so I know when I must trim the brass.

I'd do an annealing, FLZ and full brass work up every 3rd go.

I've been using dry lube media for neck sizing and bumping the shoulders. Although, yesterday I did both functions dry without any adverse results.
