Dimpling of plated bullets (NOW WITH PICTURES!)

Could be, I have noticed that I will occasionally run into a case that takes a bit more oomph to seat than most.
It never bugged me enough to investigate, especially since the brass I am reloading ( 9mm ) has multiple headstamps along with who knows how many loadings.

I always flared my casing and never had any problems seating the bullet and crimping the case. I used the single stage Lee Anniversary press and dies.

I had several Berry's skin the plating off when I first started reloading. I thought it was the bullets.
Next batch of Berry's I noticed the bullets were "slicker" like they had been pre lubed. They did not skin at all.
I since have gone to giving them a little spray of Hornady's bullet lube.
Haven't any problems since that first batch and changed nothing else.
I do NOT flare the cases at all. I only use the full length case sizer from Lee.
I then always use the Lee Factory Crimp die.

A few people have told me that shaving off some of the plating is a result of not enough flare, but it is interesting that the lube makes the difference. Just curious, have you ever pulled a pulled to see what is happening under the case rim?

Yes and it is smooth as a baby's butt.

Actually, dimpling the bullets like a golf ball might actually improve ability to maintain velocity, though only the ogive would be dimpled.
Mythbusters showed it was of some significance in increasing gas mileage in a car.
