If you can find Fiocchi or other European-manufactured .32 S&W Long WADCUTTER ctgs., they can be fired in all the "magnumb .32s and are very accurate since they are intended for Olympic rapid fire centerfire pistol competition.
I've been told that the are loaded a little bit hotter than standard .32 Long ammo because they are intended to be used in and function 100% in European-brand autoloader target pistols that have blowback actions. I don't have a chrony, so can't prove they are hotter than regular US-loaded ctgs., but have found them very effective on small game at ironsight revolver ranges, including dumping a big upstate NYS coyote from my treestand, and stopping a dozen or so full-grown groundhogs from getting into their holes. And they are tough critters.
If you shoot a bunny or a grouse with them, you can "eat right up to the bullet hole" too. I use a 6 1/2" blue Single Six in .32 H&R and a 6" S&W 16-4 ditto. Factory sights.
