I did and got a form letter reply. It mainly said something about using heavier bullets. What, 475 grains isn't enough??? :-)
Here it is, forgot I kept it:

**Tip : A heavier bullet retains its initial energy better than the lighter one
offering more penetration on a game. Bullet must expand
if it does expand properly with enough velocity, then it will generate sufficient shock for a fast, clean harvest."
Buddy of mine in Virginia bought a pound of the stuff. His sporting good store had a bunch of it at $30 a pound!
