Neck tension

[centerfire]

I don't think that you can really go wrong using a mandrel. I use Imperial graphite inside the necks.

I've been using a Sinclair for years but switched to Porter because of mandrel size availability.

I've used graphite before but still had brass galling on the mandrel. I've gone back and forth and it comes back to how much brass I'm sizing. Tonight I loaded 25 rounds of 223 and used sizing wax on a qtip. Large batches I use lanolin. Wet lubrication feels a lot better than dry from a pressure standpoint.
