I only shoot the 260.. but I can tell you this..

with a 100 grain ballistic tip, with an MV of 3350 fps out of a Ruger 77, when the Leupold scope is set on 3 to 5 power, I can shoot it without ever loosing sight picture thru the scope..

killed its first deer at 300 yds, and it was bang flop and I watched it drop dead in the scope... never lost sight picture of it during recoil...
