Bought me another Cadet, recently, "chambered" in 32-20.
Took her to the range, to see if she'd pattern, rather than group, and, much like my
last 32-20 Cadet, jacketed bullets were very accurate, and normal cast bullets had a hard time
finding the target. The 115gr RNHB bullets performed very well.
Upon inspection of the fired brass, I discovered that the fire-formed cases had no bottleneck
left. Sat down, did some measuring, and came to the conclusion I might just be able to seat a .318" bullet in the case, and get it to chamber. Well, it almost worked!
What I did find is that, if One trims the 32-20 case to 1.242" (in my rifle, any way), neck size the case 1/4" with a 32-20 seating die (ya'll don't laugh!), and seat an 83gr 8mm Nambu bullet (Graf's copper plated bullet, and mic's .3185"), the cartridge fires and functions fine. Accuracy was the best I have seen from a Cadet that had the original barrel.
Next step is to get a proper set of dies made up, and then I'll try out the 110gr RCBS cast bullets
for the Nambu, sized to .318", and see how they do.
Stay tuned.
