A friend of mine picked up a Stevens mod 26 crackshot. The caliber stamp says 32 r f, but in looking into the breech with a light it looks like a center fire cartridge. I was thinking the r f sttod for rimfire, but guess not. I am not familiar with this cartridge, any info would be helpful. This rifle is in nice shape and he wants to shoot it, I looked at Old Western Scrounger, but didn't see any ammo there. Thank you for any help.......Scott
