My dad would come back and kick my … if he knew I shot a rabbit with a 12 ga.
my dad isn't dead , and he never said anything about not using the 12 till he bought a 20ga when I was 11 for me to use all he had was a 12.
my grandpa shot everything he ever shot with that 12ga , he was the man with one gun 60 years of farming and everything and anything needed killing on the farm got a 12ga shell. those rare cases of shooting for fun , it was still the 12ga pheasants as the combine took the final rows of corn.
my other grandpa didn't own any guns , he would have pulled an envelope out of his shirt pocket and grabbed his pen and do the math that there were 25 rounds in each box but that a box of 12ga sold for 9 dollars and a box of 410 sold for 18 dollars , that it was a 9 dollar savings and compound that with you already owned a 12 so there was no need to buy a 410 to do what the 12 would do even if it was a touch of over kill.
he didn't need the paper and pen to do the math but that was how he would do it for us kids.
he did a lot of calculations for business deals however on the back of an envelope. he would work all the numbers out on the envelope then fold it up stick it back in his pocket and make the offer.
