Re: Float or not float
Years ago, Remington began Model 700 stock production with a small raised portion at the end of the stock. The theory was that slight tension at that point would stabilize the barrel harmonics, leading to improved accuracy. Many people disagree, and find that floating the barrel improves accuracy. I have used a barrel rasp to remove that area, so that a dollar bill can be slid between the channel and the barrel, all the way to receiver.
If you remove the protrusion and accuracy is not better, you can put a plastic shim in it, or small amount of fiberglass to recreate the same height as before.
