Thread: Fl sizer not sizing the neck?

I think Lee advise against annealing. Can lead to collapsed necks on the collet die.

I looked up the instructions and Lee talk about the possibility of excessively annealed cases collapsing in the shoulder but do not advise against annealing. The problem with hard necks. in the collet die, is the additional spring back leaves the necks too large to grip the projectile firmly.
GPM.

We're the dies purchased new?
If used perhaps the previous owner honed them.

Ahh yes �� my recall was hazy good that you still have the instructions

contact LEE directly....they are a good firm thats been around for a long time...Ive got two sets of RGB dies and really do rate them highly .22-25and 222 so they arent all craphola.... maybe as has been suggested yours just have wrong diamentions (the euro vs yank thing perhaps?) Lee might just stump up and send you new set with tighter neck so your cases are being shrunk down enough.its got to be worth a crack Nigel.....
