From a standing position you should be at a natural angle to the target. That is........bring the rifle straight up and it should come on target without moving left or right. For most, that is about 60-70 degrees to the target. Right upper arm should be parallel to the ground which forms a good pocket for the buttstock. Stance should be level, neither leaning a lot to the front and definately not to the back. To adjust for recoil, simply widen your stance.
No such thing as a stupid question. What is stupid is not asking it.
