I've still never fathomed the 'cost' part when it comes to bullets for hunting.
If you're doing some crop damage etc stuff and killing 500 deer a night, maybe another matter, maybe.
Well...
My dad worked his way through high school working two jobs and his parents more or less abandoned him so a family down the street let him live in a tent in the back yard. True story. He raised me a certain way... and it stuck.
But the real motivation is to stock up while components are in fact available. If there is a lull in the "values-wars" between us and the democrats and prices and availability get better... the opportunity won't be lost on me.
And... the guy that taught me to shoot was a ranger in Vietnam who went through a broken arrow. His mantra is "never run out of ammunition" So I look to buy in bulk as much as my blue collar wages will allow.
And... on my mother's side of the family there is some Scotch-Irish in the woodpile; so I am inclined to frugality because of my DNA.
