Hey Robbyhood, tell me about this proper time to punch the card. I'm new to the IBO and can't seem to find it in the rules when or even if the cards have to be punched. It says something about the shooter being responsible for accuracy and any changes have to be circled and initialed by the score keepers and signed and completed at the end of each range before continuing on to the next one. I can't find any mention of punching. I'm one who did purchase and punch to keep score(nobody mentioned anything the entire shoot) I didn't even make any mistakes and punch in the wrong spot(surprise). I thought this was the proper way and worked good as the cards are kinda hard to write on with the coating they have on them. I hope yall can forgive us folks down here. Maybe you could get it put into the rules so next time more of us will know.
