I have been loading for a couple of 25-06's for over a decade now. Although you are running a slower Roberts, Stay away from the 75gr. VMax if you want a pelt. The '06 is capable of *Almost* cutting them completely in half if hit high in the big middle. Try something in the 85-100 gr range. Although I'm not a fan of their product, Nosler's BT's are not nearly as explosive at the VMax/ TNT real of bullet.

Enjoy!!
