Ruger may have a syntheic Lott , it won't be on the shelf here , but one could order one !
I don't need a 458Lott over a 458Win , no added killing power to me , unless I go up in caliber,with the longer action (=longer throw,some times my guys short stroke our loan 375's) & more weight as Ruger factory rifles in 458 are far too heavy , I think factories make 458's heavy for the masse's who don't shoot enough to get familiar with the recoil , one or two hunts & then rub it now & again from the gun rack !

If Ruger made a Hawkeye like that one in the pix , I might look at it in Lott but would much prefer 458Win !
