Treat any copper or copper alloy bullet as if it's made from hard metal - because it is. Don't assume/hope it will open much below 2000 fps. Shoot to break bones, especially when you're working with cases that don't shred the atmosphere. (I killed a couple moose with a 225 XFB in a short 358 Winchester which had less zip than your combo. It worked great against bones even at stately speeds.) The added tip is a great improvement in the pursuit of consistent performance, especially in the smaller cases.
