Ok I am new to long range but I have already had a rifle built. It is Stiller predator long action with Shilen 24" # 5 contour pluss muzzle brake. In 300 WM and timney trigger. Jerry Stiller chambered and fitted barrel and all looks good. I ordered a mcmillian drop in stock for rifle and it looks good. I put action and barrel in stock and when i tightened the action screws the bolt binds up. I have another post asking How tight do you make the screws but I have done a little searching and found they are supposed to be 65 in lbs. I do not feel I have the screws that tight yet as i was using an L shaped allen wrench. But when I snug them down the bolt binds.
