SAUM Loaders help

My Hornady Body Die measures .540" across at the base NOT .550". What does your Die measure? Brand?

How are you measuring your die and where? What tool are you using?
Just to be specific; what caliber SAUM are you dealing with.

How do you expect the die to size brass? It has to be quite a but smaller dimensionally inside vs the fired brass thats going in. I believe my saum dies are 542 at the very bottom.

SAUM brass is measured .200" UP FROM THE CASE HEAD.
The expansion line is where the case is sized, not below this.

Cheers.

No hurry on this project. Highdrum says .542, anyone else?

The most important dimension will be the difference between the chamber reamer and sized brass from your die.

The most important dimension is what does your fired and unfired brass measure .200" up from the case head?
What does your die push the expansion line back to?
I bet your brass doesn't measure .550" just above the extraction groove either.

Cheers.

I just measured my FIRED brass .200" up from the case head, it measures .549".
Sized brass at the same point measures exactly the same, as does my 300RUM.
Unfired brass measures .545".

Cheers.

Are you dictating the Saum design must expand .010" inside the Chamber when fired? This seems like the Die Manufacturers are intentionally having everyone over work the Brass Highdrum? I was fairly certain the Norma RUM brass I have here measures .550", I'd have to dig some out Mania.

Do you think it's going to size the brass to the exact size of the die? It will not. You'll be quite lucky to get the base sized 004-005 under chamber diameter at the 200 line.

I was fiddling with the 6.8 Western Brass ... Not this time Barney.
