I have hunting friends who use 243/100TSx; 270 w/150 Fusion factory loads; 308/150 Corlokts; 30-06/Vortex 168TTSX; 25-06/120 factory CorLokt and 6mm Remington/100 factory corlokts for everything out here! A 150 anything will do very well in your '06 as will any decently made 100-120 in your 25-06. Myself, I'm going Old School for awhile with a 7x57 and whatever it ends up shooting well, ha. Have a ball friend!
