The ROTC remark made me think of my High School days when we actually has an indoor shooting range for .22. Every year there would be a Turkey shoot of sorts and all students would be invited to participate to help raise awareness and funding.
As for Arty rounds, I was on the M109 A2 which if I'm not mistaken, had a capacity of 34 rounds of 155. Pallets came with 8rds strapped together, so the math doesn't work her either!
This thread has been interesting to me. I never thought so many of us were such a complex and to put it nicely, peculiar group! Why I would bet that half off you switch ends of the Q tip when going from ear to ear while the other half uses the same end to maximize efficiency.
