^ No, I've used several 6mm rifles, but as I say, for the low-angle shooting I was doing, they did ricochet too much for my comfort level. It's just a question of degree. I was exaggerating a little when I said "big, heavy bullets" for the sake of making a point. Most of my prairie dog shooting was nearish to urbanish areas... small farms and ranches fairly close to each other, and you can't be sure of where a bullet or, almost as important, where its sound might end up. You know what happens: "Why, I heard that bullet zing right by my head --I coulda been killed," just because they heard a ricochet two pastures over.
So I figure the less metal in a bullet, the less I could have "killed" anyone with a "pwaaannng."
