Nothing wrong with a .30-06 but if you want more of a thumper it would be easy to rebarrel it in either a 35 Whelen or a 9.3 x 62. These two are nearly identical for most purposes. The 9.3 is an old cartridge that is very popular in Europe and also in some parts of Africa. U.S. shooters have noticed the 9.3 and it is becoming more popular here.
