Find a scope with 4 or 5 inches of eye relief, and mount it as far forward as the rings will allow. That's what I did with my .458, it has a Leupold 1.5x5 VX-III. On 1.5 power, it has quite a bit of eye relief, and that's still good enough magnification to get 1.5 MOA from the bench.
Also a slip-on recoil pad can temporarily increase the length of pull and sometimes this helps also.
