I got a 110 FCP .338 last month and it is a 20MOA base. My problem with it is that the base came loose today ending my range session. This was my first time out with it and it is putting them in the same hole at 100 until it loosened up. Anyone have a clue as to what size the screws are and what to torque them down to? I plan on buying a better screw once I have the sizes I need
