What's wrong with the 243 WSSM? Is she just hunting deer? If there are no SERIOUS plans in the next year or two to hunt anything bigger than deer, I'd stick with the 243 WSSM and spend the money to put some really nice glass on it (unless the Bushnell you speak of is an Elite 3200 or better). Provided that it shoots well. On deer sized game, the 7mm-08 isn't going to make them any more dead any faster than what she already has. No matter how you figure it, you're going to likely take a hit on the price of the rifle compared to what you've got into it, especially if you trade it, custom paint and all.

So unless the thing is really inaccurate or she really needs a larger caliber for larger game, or is she really just absolutely hates the rifle, my advice would be to stick with what she has.
