Very good advice, especially from JE.
I think the op is on the right track with verifying what the rifle will do with a sled. The problem is to duplicate the results when NOT using a sled. That can be very difficult-sometimes about impossible, but it does give us something to strive for.
Assuming it's a hunting gun, put a good leather sling on it. Wrap it around your arm and use it to put good consistant pressure on the rifle.
The key is consistency.
I had an old timer tell me that even when I shot off bags to put my hand between the forearm and the front bag. He said that the bag will absorb the vibrations of the gun differently than my hand will and could affect accuracy.
I'd imagine it'd be the same from the sled to the bags.
