    Neck die trouble shooting

    Hey all, so started loading up a few rounds.
    Went to use my lee neck die and all seemed fine..... until I tried a few bullets....they dropped straight in
    Strange thing is the first 16 of the 50 sized, not a problem.
    Any thoughts?
    Cheers.
    Ps Iíve read the instructions loaded 83 with the die. It just doesnít want to squeeze em down now.
    Have backed it off and also looked for a squashed collet, burred collet wings and other internet tips.
    But have yet to solve why itís not sizing. Cases are clean and all uniform in size.

    It's a Lee collet die.

    Go to a bushing type and all your issues will go somewhere a little further down the road (maybe not away but you get the idea).

    The case necks may have hardened due to multiple firings, so they spring back more after going through the neck sizer. So, anneal a few and try the neck sizer again.

    Sounds like something is different or has changed after the first 16. Some possibilities
    -The top threaded cap on the die come loose
    - die shifted in the press (loosend)
    - the brass is slightly shorter or thinner necked (different brand?)
    - the shell holder isn't push the case as high

    - something stopping the collet sliding inside the mandrel properly like a bit of grit

    Thanks for the reply guys!

    Ok so to answer a few questions:

    Yes @Mauser308 itís a lee collet die. Do you have Brand you could recommend that will neck size only and fit my lee press?

    Itís new brass, once fired, fire forming loads with trail boss. So I donít think itís your idea @rupert but thanks.

    @feratox thanks thatís a few things that I will run through and see how I get on. First itís all the same brand of brass so that can be ticked off.
    They did stick a bit the ones that did size. Then when I spotted the fault I took the die apart to see if there was grit or it had moved. Could not find any of above faults...to my eye but Iíll take it to bits again and have another look.
    I have utubed it and donít really want to go down the road of sanding the mandrel. As it was working properly.

    Cheers S

    Anymore ideas fixís will be much appreciated

    I had similar experience with the Lee collett dies.

    It worked mint in a lyman press but not in my rcbs. Ran out of adjustment with mine. I have decided to just start all over with full length sizing every time.

    Might decrease accuracy a bit but for what I need it'll be perfectly fine.

    @northdude how do you mean push a little? Side to side or up and down?
    I did have lock up a fee times with the first 16 that did size.
    Just taken it apart and noticed that there looks to be brass stuck onto the mandrel.
    I found an excellent article on them on the Lee dies on an amreican site.

    I had the same problem using the Lee collet die on my 7mm rem mag. Very frustrating after sizing a heap of brass and then find most of them hadn't actually been sized enough. Changed to RCBS neck die and never looked back. Modern does will work with just any press as the thread is the same on all of them.

    Why are you fire forming with Trailboss ?. For pretty much any bottleneck case being fireformed into something else, the superior method is to neck size the cases (and trim) but not all the way down the neck, leaving a little doughnut ring at the base of the neck so that the case is held and headspaces between that ring and the case head. Just screw the neck size die down until a point is reached that the bolt closes but the case is tight - there is felt resistance not an easy bolt drop. Then just load doughnut cases with standard loads for the forming shots and go hunting

    Each to there own...it’s what I’ve been taught it works for me, and this is not the issue.

    Anyone else with any ideas on why the die is not working.

    I took the mandrel out and gave it a sand taking off .002 still no joy. Think I’ll leave it and buy another brand as I need some loads done before I head off to France

    Must be something...I’ve done as it was work well before.

    Iwm pretty sure the collet or something stucks out the bottom of the die body and the case holder touches it and pushes up in it to size the neck

    I went to Redding competition dies, but any solid bushing die once set up is fine and won't change. I had a few odd issues with the Lee collet die - when it worked it was great but I had a few unusual things like a crimp in the case neck at odd times, or the failure to size enough, or a over size I think leading to buckled case necks on seating. I suspect just very sensitive to press handle manipulation, both velocity and force.

    Funny you say that @Mauser308 I have since solved the issue by taking the mandrel out.
    I then sized by feel. It worked.
    But I will be looking into buying a different neck sizing die..
