Weshoot2,

I'm new to ballistics and bullet performance and am just trying to figure out the effect that speed has on bullet expansion for the 240/300 XTP's and the 250 hardcast lead bullets.

In other words, will any of them mushroom less or more as the speed increases. Specifically, at 900 fps will the XTP be as likely to open up as it is at 1400 or will it perform the same through the same substance at both speeds?

Thanks for helping me better state my questions and for any help you can give.

Mike
