My RCBS Trim Pro just won't hold a casing solid enough to trim it. They spin with each turn of the handle.
I did have trouble recently with reloading some 32-20 Rifle, that I put aside and forgot to size before this but that's long been sorted out.
Now no casing will hold solid enough to trim it.
Did I forget a step in the process or something? There's no logical reason for it to not hold.
I'm using the proper size shell holders, but 38 SPL, 45, 32-20, 380? Can I be that wrong in every caliber?
Need a refresher course.
