bipods

In my experience, there is a slight accuracy advantage to sandbags.

There is a definite change in point of impact when switching between bipod and sandbags that you should be aware of though.

Exactly what Rex said. The change in point of impact ussually is more marked if you are supporting the bipod on a hard surface, less if is on soft ground.
 
Guess I'll take the opposing view on this.
Using my heavy varmint rifle (17 pounds) and my light varmint rifle (8.5 pounds) and shooting both from a bench with a rest, bench with bags, bench with bipod, and prone with bipod, there is no difference, POA to POI in any of these methods.
The light rifle is in a factory Remington synthetic sporter stock, and the heavy gun is in a factory Remington BDL wood stock.
Impact changes are primarily addressed via the way the shooter holds the rifle, which tends to change with differing support methods.
It's all about consistancy guys, hold it the same, it'll shoot the same.
 
Shooting sandbags off the bench is hard surface (rifle) to buffering soft surface (sandbag). Shooting off the bench with a bipod is hard to hard contact, and tends to throw shots a little higher as the vibration is transmitted through the bipod, causing it to bounce away from the bench while the bullet is still in the barrel.

This may not be as noticeable with varmint calibers at 100-300yd, but try it with a 300 Win Mag at 800yd and report back Michael. ;)

There is indeed a difference between sand bags and bipod.

As Ruben pointed out, the difference is more noticeable when firing with a bi-pod from a hard surface than from a soft surface.

The diffence in point of impact (POI) between sand bags and bi-pods is less noticeable when using bedded actions with free floated barrels. However, there is still some difference.
