re: cutting up a mosin VS brass rats:
I agree, do whatever you want with YOUR stuff to suit you. If you want to put your brass in the trash, please do, wish more did. The thousands of steel-case garbage littering every outdoor range I frequent would be helped tremendously.
However, if you don't want it anyway, making it harder for someone else to take what you don't want out of spite seems petty.
Funny story: Once upon a time I was out visiting friends and saw a neighbor up the block hauling a lot of home bathroom remodelling garbage out to the curb, a bathtub, toilet, vanity, etc and two large plate glass mirrors, about 3' x 4' in nice shape, he set into the bathtub and went back for more junk.
I waited for the guy to come back and asked him if he was throwing all of that stuff out (to confirm it was trash and not sitting there waiting for a buddy to pick up or something). The guy said yeah.
I asked him if it was allright for me to take the mirrors. The guy said, "Give me $20 for them and they're yours."
I asked him why, he was throwing them out, I would just wait until later that night and get them then.
He picked up the toilet tank and threw it into the bathtub, smashing the mirrors and the porcelain tank into bits, which scattered all over his yard.
"They're free now," he said.
I laughed, and when he asked why, I said, "Because now you get to pick up all the broken glass in your yard."
