Overkill seems to be the M.O. today but nobody needs anything more than a 260 to reach 400 with enought oomph! to take deer. I have shot a 270 for years and dropped a few past that target range but very rarely do you ever need to. The new 260 is a better choice IMHO. It hits your shoulder less but still packs the wallup at range. The monster 7's would be a better choice for shots way past 600 Plus, Plus.
