Lee resizing die woes

9mm cases will not enter the Lee resizing die. What could be the trouble? Thanks

Out of round is one reason why. Loose wabble in the shell holder may cause misalignment that will deform a case before it can enter the die.

If you have other brands of shellholders, then try those. Lee makes fewer shellholder sizes, for example Lee 9mm and 40 SW both use the same Lee shellholder. There is wobble with the 9mm brass.
Out of round is the most likely scenario. OOR will be visible to the naked eye.
If you have bent brass, then running it through an expander die, may be effective.
If you have brass that was walked on and flattened, then toss them. The fix is only to get them to enter the sizing die, by rounding the case mouth.

A lot of 9mm cases hit the concrete floor and get the mouth dinged out of shape , they wont enter the die

The shell holder doesn't line up properly . Check alignment of shell holder and fit of case into shell holder (some case extractor grooves are too small ) ...Lee shell holders aren't the best in the world and can give you fits ... but easy to exchange .

It may be the Lee sizer die ... I like Lee , use a lot of Lee ...but their Quality Control isn't the best ...things get out that should be trashed or some things don't get finished , like the last cut , for clearance , on the 9mm sizing die .

If it doesn't work ... call Lee on the phone and be real nice ... they usually can fix your problem ... The great thing about Lee is they will make sure you are happy .

Get an RCBS shell holder, much better. As stated the Lee shell holders that come with the dies aren’t the best, but sometimes they’re fine. Both their 9mm and .223 have given me problems and when replaced with RCBS the problems went away. This is when loading on the Lee Classic Cast turret press.

Are you talking about a few cases out of many or all cases?

Have you done anything to the cases or are they just as they came from the gun?Will they fit with the die out of the press to see if it is an alignment problem.It could be a undersized die.
