Nice to see someone interested in .32-20 and .25-20 I have and shoot a .32-30 1892 model Winchester from 1908 I have found loads from 80 gr. lead round nose to 120 gr. there are some 100 and 115 gr also. I have not started reloading this caliber yet but have found brass, which is a seasonal run so grab the brass when you find it. #6 1/2 primer and I found a guy at big lube bullets with a nice 80 gr. bullet mold. I plan on loading with black powder. The .32-20 is very mild to shoot. No real recoil to speak of. The down side is that it is on the weak side for any deer hunting. I know people can and have harvested deer with the 25-20 and the 32-20, but there are better cartridges for the job. So when I first started looking at the .32-20 I was thinking what could I use this cartridge/caliber for, well for trigger time it is fun, but more expensive than rimfire. For small game it is over kill, for turkey and coyote its great. But it is fun, not everyone has one and did I say its a pleasant round to shoot. The factory loads for .32-20 are very light. My dad is 88 years old and last week out shooting at the 100 yard range it was the 1892 Winchester rifle he wanted to shoot most. Good luck with your choice ether one will be fun.
