Every one seems to go on about the problem being with their rifles. Has anyone thought that it may be the scope. This could be the reason that shooters with the same rifle have different problems with the cold. Could also be that shooters that have free floated their barrels have more of a problem than those that have the barrell supported with a figure of eight. Worth trying my ideas. Have just tightened my ev2 down, shall see if that makes a difference.
