RE: Nosler 170 grn RN.
Both of the premium bullets mentioned above will make the old 30-30 shine. Penetration would be best with the Barnes bullet, Expansion should be a little better with the partition. The Hornady 170 has also performed well for me over the years. The 30-30 will take Elk and moose well with the right loads. My Grandpa shot elk with the 44-40.
