I’ve had my gunsite 308 for about 3 years now and love it. The issue I am having is only in cold weather. When it is below about 20 degrees my first shot is always a flyer, I’m shooting at 100 yards with a rest, the second shot is about 2 inches off and 3 and all following shots are in a 1 inch circle. If I let it sit and cool completely again to 10-20 degrees it does the same thing. Shooting during the summer is not an issue. I would like to use it for deer hunting but I can’t rely on the first shot when it’s cold outside. Any suggestions?
