Sam is going into his 3rd year of engineering school, and I've been sending him these test results.
He wrote, today: "Well I gave it a read and thought about it a bit, and I was curious about one thing. Why are cast bullets less accurate than factory made bullets? What's your hypothesis? Do you think it's just because there's more margin of error with cast lead? Is it more difficult to control quality? "
I responded: "Now, do this for me. search "jacketed rifle bullet pictures", then "cast rifle bullet pictures", look at them and comment back to me."
