Lee, I built a friend a 22-250AI on a M700 a couple of years ago. I believe he's got it in a McMillan A5 stock (not sure anymore, because he likes to swap stocks around, even though I've bedded them!?). I used a 1:9tw. Bartlein, and he's shot it mostly with Hornady 75&80gr. AMaxes. Believe me, these bullets will do a job on coyotes out at 400yds....even with fireforming loads.
