Can anybody give any info on balloon head cases, when they started how they changed and how to identify a loaded cartridge as being such. A picture I have found elsewhere and will post below shows different tapers and thickness's of the rims. Also when did solid head cartridges show up and what companys made the switch? I've read in some old archived posts on other forums of posts by 30WCF and others talking of non solid head cartridges made into the 1950's. Any info? .DT

.dirty-.thirty,

The folded head - is the earliest type having first been used in rim fire cartridges.

The solid head balloon style - Winchester patented the process to produce solid head cases in 1880 so probably soon after that the solid head balloon style cases were being produced. They are also called "Solid Head Button Pocket." Early on UMC identified these cases with a "S H" on the headstamp.
These type cases were used up until the early 1950's or so in cartridges that were originally black powder cartridges.

The solid head cases - were introduced in the 1890's in the U.S. with the advent of the 30 US Army (30-40) and the 1894 Winchester Smokeless cartridges.

Balloon style cases have no extractor groove wheras the standard solid head cases do.

The inside primed cases were military produced in the 1800's with a Benet type primers.
