Note that the description of the .38 S&W Long indicates it is inside primed. This means it is a true "balloon head" aka "Folded Head"cartridge case as current .22 rim-fires are! The primer is inside the case and supported by an internal anvil. These cases are not re-loadable! It has no resemblance to .38 S&W whatsoever except nominal caliber.
There are basically three types of cartridge cases, balloon head, Semi-balloon head aka original solid head, and current type solid head. What are currently referred to as "balloon head" cases, with the primer pocket protruding into the interior of the case, were originally called "solid head" to distinguish them from true balloon head cases which, as said earlier, like rim-fire cases. The earlier original type cases often include the letters SH within the head-stamp to distinguish the ammunition from true balloon head as they were basically indistinguishable from the outside.
The true balloon head/inside primed cases and were the only ones that had a tendency to "blow out" the rim as do rim-fires occasionally still do! The original/old-style solid head cases, again incorrectly often referred to as Balloon-head, do not blow out any more than the modern type of solid-head cases do, which is never! If there is a blow-out with a modern solid-head case it occurs on the case body, ahead of the solid-head!
