I bought abox of Hornady .451 185 grainHP/XTPs at a gun show today. It was the "old" styleblack & white box with perferated metal reinforcing strips on the corners - not the red & white box Hornady is currently using.It had a paper slip inside that I have never seen before. It states:

"XTP bullets were designed for best performance at a range if impact velocities given below. This range has been found to be optimum for maximum penetration and expansion.

#4510045 Cal-185 HP/XTP 750-1450 fps
#45140 45 Cal-200 HP/XTP 700-1250fps
#45160 45 Cal-230 HP/XTP 800-1250 fps
#45200 45 Cal-250 HP/XTP 800-1600 fps
#45230 45 Cal-300 HP/XTP 800-1700+fps "

Does anyone have a chart like this for Speer Gold Dots or Sierra Sports Masters?

(The paperalso had velocity ranges for 9MM, .357, 10MM, .41 & .44 calibers. If anyone wants any of those just say so and I'll post them.)
