which choate stock? gessing the ultimate varmint?

I never had a problem shooting my Savage with a ultimate varmint stock from bags. Actually, I thought it sat in the bags pretty good. I know the cutouts you are referring to, and it wont slide in the bags, but basically I think they were designed to shoot off of a bipod and use the mounted adjustment monopod in the rear, although I dont really like that monopod.
