hello

Bought a new set Lee Deluxe set rifle dies to reload 7 mm rem mag.
When full length reseizing once fired brass the shoulder of the case would come out with evenly spaced elongated dents around the shoulder and some with small dent just below the shoulder. Cleaned the die no change used less lube no change used spray on lube no change. Called lee was told not to put lube on shoulder did so no change. I can not see any visable defect to die. Sent them back to Lee with cases. Anyone have this problem happen to them ??
 
That is usually a sign of over lubing/lube on the shoulder. When you cleaned you dies did you remove everything and wipe everything down. Spraying brake cleaner and let it drain helps too. I think there are vent holes also on Lee dies if they are plugged could be an issue. ( I'll check mine in a bit) Let us know what Lee says.
 
Sorry - What part the shoulder is getting dents ?
If it's the taper part then too much lube .
Just lube the streight wall part of the brass only.
If it's the wall part below the shoulder is also too much spray or you have overly tight or too new die which collapsing the shoulder altogether
Pics be nice to tell better part - Biggs

I think your problem is that you are using Lee dies. Try Redding next time.
 
It is most likely a Lube issue (too much, or on the wrong place)
Your Lee dies are likely fine, all of mine are.

You don't necessarily get what you pay for, but you certainly pay for what you get. I have polished Lee dies, and made them lots better. I use the green polishing compound from Lee Valley. I took a 1/4" brass rod, and wrapped a strip of an old tee shirt around it. I spun the drill press up to about 2000 rpm and worked a bit of polishing compound into the cloth. Cleaned it well after and they sized quite a bit easier. I still needed lube, and I still could not put it on the neck or the obvious thing would happen.
 
Thanks to everyone for your opinions and suggestions I followed Lees tech instructions with less lube, went to spray lube, cleaned dies but still had problem with dents or was
very hard to seize with less lube. I sent them back for lee to see with casings. I will post lees respone when they send them back
 
Dents in the shoulder = lube on the shoulder, where there should be none. As has been said, lube only the body of the case, not the shoulder. Eagleye.
 
What is your definition of hard to size? You are pushing metal so a little force is needed, probably in the area of 35 lbs force on the handle, depending on the length of the handle and mechanical advantage of the press.
