Anyhow, if the reloaders removes the die with the case from the press before lowering the ram

Guffy - The case slides into the shell holder from the side. With the ram raised and the case in the die, how do you unscrew the die to remove from the press without backing the case out of the die?

. . . The case slides into the shell holder from the side. With the ram raised and the case in the die, how do you unscrew the die to remove from the press without backing the case out of the die?

Simple: lower the ram slightly (just enough to ease friction between case head and shellholder), rotate the shellholder so the slot for the case is opposite the slot in the ram for the shellholder, slide out the shellholder. This works for most common single-station presses, perhaps not all designs.

Since wr are dealing in thousanths, even this movement could cause inaccuracy.

Who's on first?

maybe even better, when rhe case is inserted, curn the shell holder before sizing....

No. The small amount of ram movement to ease friction lies within normal "slop" of the fit between case rim and shellholder. Done right, the case remains totally undisturbed in the die. (Shellholders are normally made with enough clearance to accept a rim significantly thicker than specs.)

What's on second.

I can not believe there are that many reloaders on this forum that appreciates that kind of answer, about the time I did not believe you could get sillier, you got sillier.

No, I said RCBS shell holders are my favorite because they do not fit unless we are talking about 'loose'. And then there are Herter shell holders, herter shell holders are held in bu set screws, to remove the die and case from a Herter press looseen the set screws and then remove the shell holder with the case and die. or lower the ram and then remove the shell holder.

The RCBS shell holder has .010" movement/clearance between the deck of the shell holder and case head. For that reason there is no reason to distrube anything. And then" If the reloader adjusted the die down to the shell holder with an additional 1/4 turn (.017") the die should make it to the top of the die without a gap between the top of the shell holder and top of the press. If when sizing cases with that adjustment the reloaders notices a gap between the die and shell holder he can measure the gap with a feeler gage.

the gap is caused by the cases ability to resist sizing, there are times it is necessary to lower the die an 1/4 turn or anneal the case.

Understand there are reloaders in the claim department that claim they have fired cases 45 times with full loads without any of these problems.

Easiest solution today would be to use a Forster Co -Ax press and not have to worry about shell holders at all.
