First of all, your barell is free floated or is touching the stock?
Using a bipod with free floated barell, without enough clearance between the barell and the stock can get you in the troubles.
Do the next test:
Stay in the shooting position, load the bipod, and ask your friend to slide slowly a piece of paper between your barell and the stock from the toip of the stock to the receiver.
Is the paper is stuck, or sliding very hard, it means you do not have enough clearance.
Remove the barell, and using a sandpaper, remove extra layer from the stock.
