A couple of years ago I purchased an H & R 32 gauge "Kaptur(?)" gun that came with the original insert for 22 blanks and one syringe and dart. I have no plans to tranquilize any annoying bulls (or bears); but it was cheap at $100 o-t-d, and I thought this little 32 gauge would be a fun gun to shoot in spite of its rifled bore (and I could also get shells locally at $10/box). So I took my prize home and quickly learned that a Fiocchi 32 gauge shell is about 3/8" too long (or my chamber was too short). I can slam the breech closed and force a chambered shell, but then the shell is so tight I have to knock it out with a cleaning rod; at which point the "extracted" plastic shell is perfectly reformed to match the forcing cone. Although the barrel must be a t least a 1/4" thick around the chamber, I'm too old and cautious nowadays to risk an experiment gone bad; so I've yet to shoot the gun, thinking I might have someone lengthen the chamber at some point. Only problem with that thinking is that I don't know anyone with a 32 gauge chamber reamer? And although I satisfied with fantasy at the moment I still think this would be a fun gun to shoot.
