Bedding a couple inches of the barrel is quite common on repeater actions, trying to make up for the lost contact area. A Crutch as NormB said, and I don't think its a bad thing, sometimes you have to.
Not an issue in the benchrest and competition shooting as most use single shots. There's also some rifles that shoot well using a barrel clamp down and an unsupported action...
The effects of accuracy difference and how relevant it is can be debated but in the end it either shoots to the users satisfaction or it does not, and if it doesn't you find which factor is causing the problem, and sometimes the problem has his finger on the trigger.
