All leupold scopes have ample eye relief for all but the worst
kicking rifles so I would agree with Jon A about moving the scope
Set the rifle on sand bags and move the scope as far forward
as you can( caution" if you shoot prone it places your eye closer
to the eye piece) so set it up according to the way you shoot,
and at max power.
The only constant eye relief scope that I know about is the
Leupold LPS at 4" at any power.
On the big bores 375,416,429 and 458's with no brake's this works
for me because it takes the slack out of your neck so your head
doesen't move forward as much.
Good luck and good hunting
