280 rem, 7 rem mag, 300 mag, 30-06. All should be accurate with enough bullet weight for the distance. I recently shot my friends encore in 300 mag and it is very accurate. My longest deer shot was 330yrds with a 30-06, the bullet passed right through and the deer did not even move. Extremely solid rest and breathing control are key, of course you have to start with an accurate rifle too.
Good shooting,
Brian
