The .32-20-115 is actually a fairly good choice "all around" if one presupposes the shooter is a careful hunter and a good shot. The loading is too powerful, strictly speaking for small game, but the careful hunter will take head shots at small game distances and negate this problem. It is not powerful enough for large game, strictly speaking, but the rancher or farmer or woods loafer who knows his territory and can stalk close can overcome this shortfall in the cartridge as well. The same thing for varmints; 200 yard shots won't work, but a careful stalk and shot will.
Mattern (in the 1920's) remarked that the .32-20 was once the most popular cartridge for handloading because more shots could be fired in its blackpowder loading before cleaning was needed than any other. He said it was a good 150 yard hunting cartridge, but groups on target were typically spoiled by a flyer or two. This last has been my experience as well, with a Low Wall and a Savage 23. The overall economy in loading the cartridge is also quite an advantage.
In the past, somebody who was mutating a cartridge for some reason or another always modestly put his name on whatever the new (and "improved") version was. Why has the hapless .32-20 been denied this shift of blame? If the weird specialty twists, bore diameters, extended length bullets and increased pressure versions were called the ".32 Klanghonk Express" or something, then we could be saying that
that was the bad cartridge all-around. "(*Sob, sob*), Leave the .32-20
alone!!"
