This is for 6.5 prc using redding series B dies. I always have used Lee lube and have never had this problem with other calibers. A very thin swipe of lube on the case and inside the neck has always been good. It seems I have to lube the body more or actual sizing requires quite a bit of force on the press. I am sure its the lube that is denting the neck but with the extra I am adding to the body is obviously pushing lube to the neck. Different lube help maybe?
 
If you haven't already, take the dies apart and really clean them. I have had dirt and/or lube build up in the neck to cause dents, so technically it's too much lube but it may be too much old lube
 
OP, can you confirm that the dent is on the case neck, not on the shoulder of the case?? Have seen many dimpled shoulders due to excess lube, but not certain that I have seen a neck dented??
 
Yep, I meant shoulder not the neck. I know its the lube but it just seems I have to lube the body more generously than ever before to be able to run the case all the way up. I will try polishing the inside of the die
 
Clean the die out of all old lube, and when you lube the cases wipe the neck and shoulder off before sizing. And make sure the dies vent hole is not clogged.
 
If you are sizing a few cases, the case lube technique does not matter very much. If you have a bucket or two of brass to size, there is a fast efficient way to lube the cases. I lube 100 or so cases (rifle) at a time. Takes about 30 seconds.

I use Lee case lube. It is a water soluble cream that is easy to clean off.

Dump brass in a plastic pail that has a lid.

Then take a 1" worm of lube and smear it around the top inside wall of the pail.

Put lid on and swirl and shake for 15 seconds. This will lube all the cases and deposit a tiny dab on the case.

 
^^^ old man's method is the best way to lube and not over lube.
On the rare occasion I'm doing a small lot, I will only lube about half way up the case with my finger, maybe 3/4 but always leave an inch below the shoulder.
 
I'd guess overlubing. (Experience is a good teacher)
I do something like the pail method listed above but I use a large zip Lok. The bag takes less space on my bench, I keep reusing it
I do not thin the lube with water, I use 99% rubbing alcohol.(cheapest source I found is a feed store in 4l jugs) It evaporates fast, as I size them after the Lee lube dries. I don't have the neck dent problem anymore.
 
I've switched to the imperial sizing die wax and have found it to be far superior to the Lee case lube and is less prone to build up in dies. A very thin application is all that's needed. I also shy away from putting any lube on the shoulder.

I can't comment on the Redding dies, but i found the cheap Lee dies to be more susceptible to neck denting from lube buildup than higher end dies.

FYI.. break clean works well to remove the excess lube & clean your dies. Just be sure to size a couple cases and apply a light oil to the outside of the dies prior to storing your dies to prevent corrosion. I also keep a desiccant pack with my dies to suck up any moisture.
