bigbore,
the .35 whelen is an excellent round , and it will handle all of north america' s big game if loaded properly , some here say that it kicks but , my whelen a remington model 700 classic doesn' t seem to kick at all , in fact my ' 06 gives a stiffer push in my opinion.
another good round would be the .338-06
or you could go all the way wildcat and go for a .400 whelen,
i think rcbs even makes dies for it ( but don' t quote me on that ) , it' s a .40 caliber based on the ' 06 shell , it' s not a magnum but will be enough gun for north american game
