308 full length sizing issue

[bigedp51]

That was my first thought but at second glance the majority of the dent is on the side of the case and extends a little into the shoulder. If this was a lube dent there would be a huge glob of lube remaining on the case and subsequent sized cases would have dents of decreasing size as the excess lube transfers from die to case.

He is using synthetic motor oil for his case lube and its not going to stay in one place. His next problem will be a blown head gasket and smoke coming out of his tail pipe.

Normally real thicker case lube collects in the shoulder area of the die and causes shoulder dents. His problem is the "motor oil" is running back down hill in the die and a new oiled case is then pushed back into the die on top of the old oil in the die.

I know the Lee dies I have GUSH oil when I'm in a groove doing .223 and 416 Barrett.

I still want to know if he is using a small base die without a vent hole or blocked vent hole.

Again, not a lube issue. I lube one case, then run half a dozen. I've used this same method for 10 years with no issue on my other bottleneck cases. Only started with 308.
