Shallow primer pockets on vintage brass
I recently acquired some .32 S&W brass. This is the short version and most of the headstamps are very old.
The brass is manufactured slightly differently than current brass.
The head of the case is not solid. The primer pocket is a raised dome in the bottom of the case, not just flat with a hole like the current production. The primer pocket accepts a new primer but The new primer is way too tall to fit in the pocket.
The pockets are about 0.092-0.094" deep vs the new ones at about 0.119" deep.
I have learned that these are Semi-Ballon head cases as in example #4.

I guess these need to go in the novelty brass box, since they will not accept a primer. Too bad, as I have nearly 50 of them in all sorts of headstamps.
Unfortunately, I really needed something that I could feed my son's new Iver Johnson break-top.
