Dented case while resizing. PICs now up!

I see one big dent and what looks like small wrinkles also on the shoulder from reforming the shoulder. I would do what Dogleg stated in his posting and back off the die. I would also compare a fired case side by side with a sized case and see how much the shoulder dimensions are changing. It may just be a excess buildup of lube in the dies shoulder area so make sure the vent hole is open

Clean the die and wipe the case shoulder and neck off after lubing before sizing. And remember sizing will force any excess lube on the case body upward and onto the shoulder area.
 
YUP dent will shoot smooth again then on the third firing the case will split where the dent was. Most likely blame the poor brass manufacture at that time.
 
Some good info listed above. I have found that sometimes I have to use a different lubes. I have a 450 Rigby that I have to use bee's wax as spray or liquid lubes cause issues. I found that straight wall cases seem to size better with bee's wax. Everybody's situation will be different of course.
 
RT,
How did you make out in the end?


So, did like everyone said and I took the die apart and cleaned it. Seemed to solve the problem, but I only ran three more cases thru it and broke the de priming pin. So once I get another pin Ill be able to give it a real try.
