I understand that to much lube may cause dents dings and shoulder issues. Can't seem to figure it out in my head. Would someone explain why?
 
A lot of this depends on the brand of die used, the brand of lube used, whether the die manufacturer can consistently drill the pressure relief hole in the right spot, and whether the die user keeps the pressure relief hole cleaned out. With some brands of dies and lube (which I will not go into here) it is very
difficult to put too much lube on to dent a shoulder provided the pressure relief hole is cleaned out. OYE
 
That little hole that may or may not be drilled in the threads near the top of the sizing die.
 
Sizing die vent hole:

It is located at the shoulder point on bottleneck rifle sizing dies to let air pressure & excess lube out.

But I have never found them to be too good at that.

Excess lube will still result in shoulder dents every time.

I find that most of the locking rings end up covering the vent hole. Kind of hard to get a good vent if it's sealed up. Works for awhile till some lube finds it way into it. The OLD RCBS Lube (Jel) was terrible at this.

That depends on what brand of dies you are using and what lube you are using.
With Lee rifle dies and using Lee lube, the only time I ever dented a case was when the pressure relief hole was stopped up. The only time. I routinely get too much lube on the case and it squirts out the hole. I smear the lube on a damp sponge and roll the case in it and I don't care if it gets on the shoulder either. Smear a little on the inside of the neck with a q tip. I always clear the hole before I start. The hole has to be drilled in the right place to work. OYE
 
Back before I started using a spray on lube I would sometimes get lube dents when resizing, and the vent hole did nothing to prevent the dents. Too much, or misplaced lube, will always cause dents, regardless of whether or not the die has a vent relief hole.
