I bought a used set of Lee Dies and the full length sizer apparently puts a dent in the case shoulder. Will try to post pics, but basically it puts a 'diamond' shaped dent, running top to bottom, in the shoulder.

Are these cases ruined?

I tried to visually inspect the die interior, and scrubbed it out with solvent and a copper brush, I cant see any obvious defects... but the cases are still being warped.

Why? and is this any good?
 
dented cases

you are probably getting to much lube on the cases. A little at top of the neck and on the body but do not get any on the shoulder.
good luck

thats all I use, and sparingly at that.

Here's a picture of the end result:

too much lube. Under pressure, the excess has to go somewhere. It created a where.

If they fit in your rifle, you probably have a high pressure case former that will correct them, but it depends on what the dents look like.
 
there are certain cals that I lube every second or third case.

some I run a dry case through every 3 or 4...

I use Lyman case lube on an RCBS pad.

it's reasonably thin but buildup in the dies seem worse with some cals than others.

my whole life is trial and error...

huh.

I did one without lube and it came out fine. Can someone explain to my why lube caused that?

The lube can't compress under pressure, something has to give and the soft brass of the case becomes the 'where' as another poster so aptly noted.

You don't need a lot of lube. I usually do five at a time, one quick roll, check to make sure too much lube wasn't deposited and on to the next batch. You don't need to press super hard on your lube pad either.

If you're still having problems, you might try an aerosol case lube. More expensive though. Hang in there, you'll figure it out with a little more experience. All the best!:)

Sounds like you have received lots of good advice, but there is one thing that I will mention, and some of the other fellows may know more about this. I have a few Lee FL sizing dies and have noted that they often have a tiny hole drilled through them near the shoulder area. I notice this on one that was always putting a fine scratch on each case and I traced it to some flakes of metal that were stuck into this hole. I presumed that it was intended as a relief port for air or lube, but that was just my guess. Anyway if it is intended as a relief and is plugged this may have a bearing on why you are experiencing the hydraulic denting on your cases with very little lube used.

Another good point, on my x54r LEE FL die when I had the set properly the breech lock rubber o-ring was right on top of that hole which caused it to have no place to vent. So i had to be careful because even a small amount of "too much lube" would cause the dents.

On your second point of the hole scratching I have had that problem too, not sure how it started but I noticed small scratches in the shoulder. I cleaned the hole with a needle and there was a burr inside the die so I rubbed it with the wood end of pencil for a while and took the burr off/bent it off, worked good.

Now a little lube, nice sized brass and no scratches.
 
In the front of the reloading manuals they tell you to wipe the lube off the necks and shoulder. :eek:

All the information in the world is written in books , and all you have to do is read.

From the reloading manual.

"90% of all resizing problems are from excess or no lubrication" ;)
