AGS' story is very interesting. I have several Cadets in various calibers, one of which was given to me in the 1990s by and old friend that was moving most of his guns due to his age. He was quite generous with "stuff" his children/grandchildren didn't want. He had been a dealer when the cadets were commonly on the market. The one he gave me was a very nice .310 in original form. He kept another one, even nicer, that he had converted to 32-20. He didn't rechamber it though, rather, he ground/polished the face of the breech block back enough to make up the difference in rim thickness. Since the .310 cartridge used a heeled bullet that was outside lubricated and about the same diameter as the case, the throat was long enough to chamber a 32-20 cartridge. I speculate that the forward part of factory 32-20 bullet (he handloaded but didn't cast bullets) could enter the rifling. He claimed fine accuracy, but I don't know if he had a .316" or .323" barrel. It might be that AGS' rifle was converted the same way and the .310 heeled bullet makes the 32-20 cartridge long enough to "jam" the bullet into the rifling. My cadet in .357 Mag. has a similar problem in that a .357" SWC bullet seated to the crimping groove won't chamber. I speculate that when it was rebored and chambered a pistol reamer was used, rather than a rifle reamer. I just seat the bullets deeper but mostly just use 38 Special ammo. BTW, my cadet in .310 shoots great with the .310 bullets, self-modified 32-20 cases and Unique. Before I had the correct mold, I used the LYMAN# 32359 bullet by overexpanding the neck, seating the bullet, then running it back into the sizing die (I was using 32-20 dies at that time). This swaged a "heel" onto the bullet. They shot well, but the cases didn't last long.
