7-08 to the 338 is a huge range of caliber and cartridge....There's been lots of opinions and a little infield to back anything ....I have made a choice and will go with the 300 WSM .... seems is will break a elk's shoulder at 350 yds and the 7-08, 280 rem ect : is questionable...thanks again for all the help...
The elk antlers I posted pictures of didn't grow on the wall.

OP,
To answer your question, A 300 Win mag with a 180 Grain bullet, or a 30.06 with a 165 grain bullet would be my choices. As long as the shooter can competently handle either rifle, your in business.
