If you HAVE to choose between the 30-30 or 35 Rem..... I'd go with the 35 Rem with 200 Gr Rem Core-lokts. That's probably the biggest "omph" of the two. However the 444 Marlin or 35 Whelen will give you a lot more "omph" for a little bit more money. Of all four, I'd take the 35 Whelen in a pump, but to each his own.
