I ran into a problem that I have not encountered until just recently. Thought perhaps I could get a little help on this thread.
Previously, I had noticed and read about shoulder dents caused because of using excess lube during resizing. Recently, in resizing a bunch of 257 AI cases I couldn't stop the old brass from denting. It didn't seem to matter how much or little lube I had on the case. Any idea what happened ? The resizing die hasn't been changed. The chamber is the same. The load is the same, etc. The only change I can think of is that the brass is getting old and perhaps it has changed somewhat. I trim my brass after re-sizing and I didn't notice any unusually lengthening there either. I have not tried the dented cases in the rifle chamber yet. That might tell me more.
I plan on shooting the dented cases just as normal because from my previous experience with a few dented cases and from what I've read, the dents shouldn't cause any problem.
Anybody got any ideas or advice what might have happened to cause the dents?

My guess is you have excess lube in the die it self. Try cleaning the die then run a case through it.

Clean the die and try again. The lube can build up in the die and collect at the shoulder denting otherwise lightly lubed cases, it doesn`t take much to cause a dent. I`d also check the vent hole in your die if it has one it could be plugged also, I had a die that you could watch the lube "breath" in the vent, going out of the die body when the case went passed it and sucking back in when it was withdrawn. Needless to say the die was in bad need of cleaning and did cause some minor dents. I did wipe the interior of the die and thought I had the problem fixed, I didn`t that`s when I found the vent was plugged and feeding more lube to the body.

brake cleaner applied liberally into the die body, then wipe it dry and try again.

1. Take the die apart and clean it.
2. Get yourself some spray-on RCBS case lube. Since using the spray stuff, I have had zero case dents after thousands of handloads.

Thanks to all for the tips. I'll check the die vent and clean the die of excess lube. I'll bet one of those tips do the trick. Thanks again.

I've found the same as Ol' Joe, the vent may be the problem. Clean that and the inside of the die, and I'd bet the dents depart.
