Re: 32/20 for hunting
Factory loads with the 80 grain bullet were capable of 780 ft lb muzzle energy according to Cartridges of the world. Barnes says "much too underpowered for deer" Although in a strong action with hand loads, it was possible to reach 1,000 ft lbs of ME.
As I recall, the PA buck record for several decades (1920s to 1950's) was a deer shot with a 32-20.
I have a single shot Australian cadet rifle in 32-20 that is quite accurate. I use it once in a while for groundhogs.
