Lee Case Trimmers

Has anybody had a problem with these getting shorter after 500 cases or so?
I have one for 357mag, 38spl and 9mm (I know not really necessary for 9mm) and all are getting shorter which makes sizing them pointless as they aren’t all uniform. The 38 one is now undersize.
There is a small bump in the case holder maybe that’s burring the edge of the trimmers over I am doing them by hand so not overdoing it with a drill.
I have emailed Lee to see what they say.

I don't trim any of those cases. But no, my Lee case trimmers all seem to be the same length they started. I chuck the case holder in a drill and run the trimmer and guage in by hand.

Does it look like the pin on the end of the gauge rod is bent or wearing down?

The edge of the pilots are burring over as if they are squashing flat. It can’t just be a bad pilot as it’s the same on all 3.

What are you calling the pilot? Can you post a picture?

I don't trim pistol brass. The one I have for trimming 223 has trimmed at least 5,000 cases and still trims to the same length.

By pilot I mean the part that screws onto the cutter (the bit you change for each calibre)

That is the gauge. The trimmed case length is the distance from the shoulder to the tip of that gauge.

The shoulder should not be deforming. How tight are you screwing it in? Finger tight is plenty as long as the shoulder seats against the flat of the cutter.

I dont really understand exactly what part you are saying is getting shorter? The pin on the end of the pilot? the shoulder on the threaded end?

The pin on the end of the pilot/gauge is getting shorter.
Yes I screw it in finger tight in fact I have had to use thread lock and back it out a bit on the 38spl one to get it to cut the correct length.

Call LEE and ask them to replace them.

This is what Lee said about it.

Because you are pushing the gage hard against the lock stud, you are just peening over the end of the gage, making it shorter.
The shorter the gage, the shorter the case. When using power to turn the lock stud, you have to stop pushing as soon as it stops cutting, or you just deform or wear out the pilot pin.
The small bump could be causing the problem also. Rub the bump against a knife sharpening stone until it is gone.

I guess I need a different make of cutter then I arent pushing any harder than you would need to

Lee are now sending me a new 38spl gauge
I have flattened the bump in the case holder so hopefully it will be ok from now on.
I haven’t used any more pressure than is needed to cut the case so hopefully it will not happen again.
