I have been using a Lee Collet die with my 22 hornet cases for about 8 years now and everything has been great.
Last night I had 175 cases that needed to be sized and I screwed it in and went to sizing. On about the 100th case, instead of sizing the neck, it pushed the neck about halfway down into the case. I tried another one slower and it got resistance so I backed off but the case was ruined anyway.
I decided mayby the die needed to be cleaned. I took it apart and cleaned it really good and put it back together. The test run ruined another case. I decided to oil the shaft and collets. Tried again and got the same results.
Question:
What in the **LL am I doing wrong?
I thought I would see if anyone else has an answer. If not I will be sending it back to Lee, but that takes time and I am impatient.
