The .416 Ruger or a 404 Ruger is an easy build on a Mauser or a Win. m-70..The .416 Ruger I built sometime back had all the bells and whistles and I used Talley QD with a slip on Talley peep..It worked like a charm with irons or scope. I got 2400 FPS with a 400 gr. bullet in a 20 inch tube with no problems at all.
It would be a snap to put a Ruger wood stock on the Hawkeye with a glass job, and you can pick up a Ruger factory wood stock used for next to nothing.
