Hi, I know there's lots of experience here on the subject. I'm shooting a 500 Jeffery at what is essentially 500 NE velocities (570g bullet at 2175 fps), which is the point at which I can swing and shoot the rifle naturally without being overly concerned about recoil.

My question is what expanding bullet(s) do you folks recommend for cape buffalo and Alaskan brown bear, realizing that these may be two different bullets. I want something that will expand to close to double caliber, but will penetrate and hold together. I'm shooting 570g TSX's right now, but am a little concerned about them opening up at these velocities. I know North Fork plans to come out with their soft points in .510 caliber soon as well, and of course a the 570g and 600g Woodleigh Weld Cores and Protected Points are in the mix as well.

Thanks much,

Chuck
