Jeff:

It is not a bad joke, I made the half cut with a "sacabocado" (cardboard cutter to make round taps)in a pedestal drill. I put an stop in the drill, so each cut have the same deep always. Every shotshell altered in this form make the shotgun function perfectly. ZERO malfunctions in more than 3 years.
1 oz Spanish "Escopesa J & G" shotshells.

Best regards,

Jose
