I checked this with my 7mm08 in plastic stock and found point of impact was indistinguishable from bipod and sandbag/ front rest with rear bag so I use them interchangeably for sighting in . I prefer the sandbag system as I think grouping is a smidgeon better. They are around 1 moa.
Once I go to unsupported prone and sitting my groups are more like 3 moa. With either position using a rest like backpack or post it's more like 2 moa. So, again, a minor change in mean point of impact wouldn't be detectable. I'm very happy to use bipod to sight in even though in principle the point of impact could differ from in use hunting. I dont use a bipod for hunting, only for practicing.
