Question about Lyman Universal Case Trimmer

[bigarm]

I was setting up to reload for 30-30 today. I had some once fired brass. I had a Lyman Universal Trimmer that I had not used before. As per directions I sized and decapped the brass. I then tried to set up the trimmer to trim the brass. I had a horrible time. Could not get the brass in deep enough to trim. Finally out of desperation, I changed the pilot to the 28 instead of the 30 so the brass would go far enough on the pilot to trim. It worked, but my question is what am I doing wrong?

Assuming your case neck has been sized to the correct dimension, your pilot may be slightly over size and you need to use some fine sand paper to reduce it. I had the same problem with 45 ACP brass and this resolved the issue.

Most of my Lyman pilots have been shaved. Chuck the pilot in a drill motor and use a piece of 400 grit paper until a case slides on. It can't be tight or you won't get the case off, because you will get a burr.

I've had good luck with my Lyman Trimmer.

My .30 pilot measures .303.

The case necks on my resized 30-30 brass measure .307.

If your pilot is oversized, the other guys have good ideas about trimming it down.

Size, decap & expand. Make sure the expander is the correct diameter, about .307" If the expanded neck dont fit, adjust the pilot.
