I agree with Dan, Old John had it right..a bullet that does it both ways..a softer nose to expand in softer tissue, and a bone crushing core to penetrate. I'm sure the TSX is a good bullet, and if there are issues with expansion, I hope they can be worked out. I have not shot any TSX's in any of my rifles, but I hear good things about their accuracy. I did buy a box of 85gr 243's to try...testing bullets in the lab with "ballistic gell" doesn't tell the full story...the shooting public will be the jury.
