RE: Big game rifle
Myfavorite elk round is the 338-win. mag.
Other good choices would be, 340-weatherby, 338-R.U.M., 300-win. mag, 300-Weatherby or 300-R.U.M.
Any of the six rounds I listed willwork great on elk & bears.
I also recommend premium bullets. Nosler Partition,Swift A-Frame or Barnes-Xtoname a few.
