Hi
Cull over 150 red deer every year with .270 win fitted with a moderator, excellent rifle. it is a variant of the 30.06 reduced to approx. 7mm Digests all ammo well. You might find the following article interesting http://www.chuckhawks.com/270family.htm
I have been using a 110 grain Hornady Vmax factory loaded by Norma recently, it is extremely effective on everything from fox to red deer stags.
