nce I reload, I will place them in my order based upon what I have guns for...
FWIW I based my earlier list on the premise that we were talking about average retail prices for commercial ammo.
Regarding your list:
.38Spl is marginally more expensive to handload than 9mm Luger only because the bullets tend to be a little larger. (The cost of commercial component bullets generally increases with weight first and caliber second, although less popular calibers are pricier due to lower demand.)
.357Mag is marginally more expensive than .38Spl because brass costs a bit more, but the cost difference matters little in the long run because case life is almost indefinite. One of the niceties of handloading .38/.357 is that the brass lasts a long time; it's thick and therefore durable, and since it's a revolver caliber, fired cases don't get lost in the weeds (outdoor range), thrown forward of the firing line (indoor range), or chewed up by the extraction cycle.
Both are less expensive than .45ACP or .40S&W, which are near-tied.
As lamarw implies, handloading .32ACP (and .25ACP) is a notorious PITA because the case volume is small relative to the volume of the powder charge, making them unforgiving of overcharging or too-deep bullet-seating depth. Although this is a problem with many automatic pistol cartridges, it's greatly magnified with .25ACP and .32ACP because the cartridges and powder charges are so small; what would be an inconsequential error in a larger caliber becomes potentially catastrophic. Many people who handload these cartridges individually weigh every single charge and measure the length of every cartridge, guaranteeing safety but greatly increasing the loading time.
