Full length sizing die bottoms out on shell holder but doesnt bump shoulder back enough.

I ran into this with 2 different rbcs die sets/shell holders. Instead of removing material from the sizing dies or shell holder, I was able to cut some .010 stain less shim to fit in the bottom of the shell holders to raise the case .010 into the sizing die. Problem solved.

I had this issue with a Forster die. I just sent it in and had haem cut it down a few thousandths. Turnaround was about 2 weeks.

Do you de-prime before sizing? I assume so, otherwise the shim wouldn't allow the primer to fall through.

Ditto. Had the same issue with both a Forster and Redding Die. Send back the die with some fired cases and they shortened the die. Both conpanies have excellent customer service.

Agreed on the customer service, and I have used it in the past. These days I’m too impatient, if a sizing die is too long I take a little off the bottom with a sanding disc on my angle grinder. Takes 5 minutes or so.

Fine wet-sand sandpaper and a little oil on a hard, flat surface works pretty quick and it's easy to keep the die bottom square. Take a few strokes and rotate. Check with calibers.

I've done this, works very well and goes quick. Make SURE you clean the die super well before running a piece of brass. The grit from the sandpaper will scratch up your die otherwise.
