Expansion velocity for 570g TSX

Hi, I'm shooting 570g TSX's out of my 500 Jeffery at 2300 fps. Anyone know what the minimum reliable expansion velocity is for these bullets? At close range the expansion is pretty dramatic.

Regards,

Chuck

You may want to call or email Barnes and ask them. I wanted to know the same thing about the 180 gr 30 cal TSX bullets and they said the minimum velocity is 1600 fps (if I remember correctly). I asked them various other questions and they were more than happy to answer.

It's already half an inch wide, how much more do you need?
