Neck lube

Imperial dry neck lube if you must. I only find it necessary sometimes on new brass. After firing leave the carbon on the inside of the necks. Stroke a nylon brush in and out of the neck. If you are sizing the neck properly after firing there shouldn't be a need for neck lube. YMMV
 
small squirt of One Shot works just fine and dries, so no harm will come to powder when it is put in, prior to bullet seating.
 
I played with this 2 years ago. Stayed with carbon in the neck and 1 pass with a nylon brush. On a similar subject I have a statement a couple of weeks ago about necks thickening. I was told I was wrong, I knew I wasn't. So, I loaded 6 BRXs last week and saw the seating force jump from 20 - 25 to 40_45. I measured by cut .262 necks and found they had went from .00850 20 about .00852 to .00853. That was after 3 firings. Yes they do get thicker and it is the single biggest factor to increasing seating force I have found. Of course if you don't care sbout seating force it does not matter. I have found keeping this lower and consistent keeps the rifle shooting consistent also.
 
I do not think it effects impact point but graphite or moly definitely effects seating force. If I was using light neck tension, I would brush the necks and seat. Using a lube makes the bullets easier to move. With light tension and graphite you can pull the pulleys out with your fingers. I don’t think that is good.

This is why i run them back over with my preset neck turning tool. If it cuts then you know they had to have gotten thicker (they cut at least a little bit not all the way around pretty much every firing). You cant get consistent neck tension or runout if they grow on one side every time
 
Be careful. You can open a whole nother can of worms if you are not careful to size down the entire neck all the way down to the shoulder before you re-turn the neck.
